You might change the water once a week and clean the filter once a month, but you feed your fish every day. That is why picking the <strong>best fish food<\/strong> makes such a big difference. Good food gives your fish bright colours, strong bodies and a longer life. Poor food, or too much food, does the opposite. It clouds the water, feeds algae and makes fish weak.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The good news is that you do not need ten tubs of food on your shelf. Most tropical tanks only need one good daily food, plus one or two extras for the fish that live at the bottom or need something special. In this guide, I will walk you through how to choose, which foods work best for which fish, and how to feed them the right way.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why the Right Fish Food Matters<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In the wild, tropical fish eat many different things. A tetra in a South American stream will snap up tiny insects, worms, algae and bits of plants all day long. A catfish will dig through the riverbed for small creatures and leftovers. In your aquarium, your fish can only eat what you give them. So their whole diet depends on you.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The right food gives them the protein they need to grow, the fats they need for energy, and the vitamins they need to fight off illness. It also brings out their natural colours. A neon tetra or a guppy fed on good food looks far brighter than one fed on cheap, dusty flakes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Food also affects your water. Every bit of food that your fish do not eat starts to rot. As it breaks down, it releases ammonia, which is harmful to fish. Good food is easy to digest, so fish turn more of it into growth and less of it into waste. This is one of the simplest ways to keep your tank clean and stop problems like <a href=\"https:\/\/bluviva.com\/cloudiness-in-aquarium-water-7-causes-how-to-clear-it-fast\/\">cloudy aquarium water<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Makes the Best Fish Food?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Before you buy, it helps to know what to look for. Here are the main things that separate a great food from an average one:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Good protein first.<\/strong> Look for fish meal, shrimp, krill or insect larvae near the top of the ingredients list. Most tropical fish do well on foods with around 38% to 45% protein.<\/li>\n\n\n\n<li><strong>Some plant matter.<\/strong> Spirulina and other algae help with digestion and colour, even for fish that mostly eat meat.<\/li>\n\n\n\n<li><strong>The right size.<\/strong> Small fish need small granules. If the food is too big, they cannot eat it, and it will sink and rot.<\/li>\n\n\n\n<li><strong>The right level in the water.<\/strong> Some foods float, some sink slowly and some sink fast. This should match where your fish like to feed.<\/li>\n\n\n\n<li><strong>Added vitamins.<\/strong> Vitamins A, D3 and E help keep fish strong and healthy.<\/li>\n\n\n\n<li><strong>Low waste.<\/strong> Food that holds together in water and is easy to digest keeps your tank cleaner.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Top, Middle or Bottom: Where Do Your Fish Eat?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This is the part many beginners miss. Fish do not all feed in the same place. If you only drop in floating food, the fish at the bottom may never get a proper meal. So take a minute to watch your tank and see where each fish likes to eat.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Top and middle feeders<\/strong> include guppies, mollies, platies, tetras, rasboras and bettas. They are happy to grab food near the surface or as it slowly falls through the water. Slow-sinking granules are perfect for them, because the food stays in reach for longer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Bottom feeders<\/strong> include corydoras, loaches, plecos and otocinclus. They search the ground for food and rarely swim up to the surface. They need food that sinks quickly and stays in one piece on the bottom, like pellets, nuggets or wafers. If you have a mix of both, which most community tanks do, you will want one food for each group.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Best Fish Food for Tropical Fish at Bluviva<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Below are our top picks, sorted by the kind of fish they suit best. I have kept the list to foods that really earn their place, so you can build a simple routine without wasting money.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. StreamBiz Universal Granules \u2013 Best All-Round Daily Food<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If you want one food that suits most community tanks, start here. <a href=\"https:\/\/bluviva.com\/product\/streambiz-universal-granules\/\">StreamBiz Universal Granules<\/a> are a balanced daily food made for small to medium tropical fish that eat both meat and plants. The recipe uses fish meal, spirulina and wheat, with 40% protein and added vitamins A, D3 and E.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The granules sink slowly, so fish in the middle of the tank can feed in a natural way, and fish near the top can catch them as they fall. They are easy to digest, which means less waste in the water. It comes in 40 g and 80 g tubs. For a tank of tetras, rasboras, platies and similar fish, this is the food I would reach for first.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Best for:<\/strong> mixed community tanks, beginners, everyday feeding.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. StreamBiz Tetra Natural Granules \u2013 Best for Tetras and Small Shoaling Fish<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Tetras have small mouths and like small, frequent bites. <a href=\"https:\/\/bluviva.com\/product\/streambiz-tetra-natural-granules-40-g\/\">StreamBiz Tetra Natural Granules<\/a> are made with this in mind. They contain fish meal, spirulina and algae, with 40% protein, and they sink slowly through the middle and upper parts of the tank, which is exactly where tetras swim.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The added algae and spirulina help bring out the red and blue in fish like neon and cardinal tetras. It comes in a 40 g tub, which is a good size for a small or medium tank, because the food stays fresh until you finish it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Best for:<\/strong> neon tetras, cardinal tetras, ember tetras, rasboras and other small shoaling fish.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. StreamBiz Guppy Granules Colour \u2013 Best for Guppies and Livebearers<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Guppies, mollies, platies and swordtails are famous for their bright colours, and the right food makes those colours stronger. <a href=\"https:\/\/bluviva.com\/product\/streambiz-guppy-granules-colour-40-g\/\">StreamBiz Guppy Granules Colour<\/a> include shrimp meal and astaxanthin, a natural colour booster that helps reds, oranges and yellows show up well.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With 38% protein and spirulina for plant matter, it suits livebearers, which need a bit more greens than many other fish. The granules are small and sink slowly, so even tiny guppies can eat them easily. It comes in a 40 g tub.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Best for:<\/strong> guppies, mollies, platies, swordtails and endlers.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. StreamBiz Immun Plus Granules \u2013 Best for New or Stressed Fish<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">New fish are often stressed after the trip home, and stress makes them more likely to get sick. <a href=\"https:\/\/bluviva.com\/product\/streambiz-immun-plus-granules-80-g\/\">StreamBiz Immun Plus Granules<\/a> are a complete daily food with extra support for the immune system. They contain beta-glucans, garlic, brewer&rsquo;s yeast and herbs, with 43% protein.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I like to use this food for the first few weeks after adding new fish, after a water problem, or during any time when the tank has been through a change. Garlic also makes the food smell stronger, which can tempt fussy eaters. The granules sink slowly and come in an 80 g tub.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Best for:<\/strong> newly added fish, fish recovering from stress, and picky eaters.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. StreamBiz Spirulina Granules Indian Almond \u2013 Best Plant-Rich Food<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Some tropical fish need more greens than others. <a href=\"https:\/\/bluviva.com\/product\/streambiz-spirulina-granules-indian-almond\/\">StreamBiz Spirulina Granules Indian Almond<\/a> contain at least 5% spirulina plus Indian almond leaf powder. Indian almond leaves are well known among fish keepers for helping fish feel calm and settled.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With 42% protein, it is still a complete food, not just a snack. It works well for livebearers, many cichlids and any fish that likes to nibble on plants. You can also use it as a second food a few times a week to add more variety. It comes in 40 g and 80 g sizes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Best for:<\/strong> mollies, many cichlids, and fish that eat both plants and meat.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6. StreamBiz Bottom-Feeder Pellets \u2013 Best for Corydoras and Loaches<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Bottom feeders often go hungry in a busy tank, because faster fish eat everything before it reaches the ground. <a href=\"https:\/\/bluviva.com\/product\/streambiz-catfish-nuggets\/\">StreamBiz Bottom-Feeder Pellets<\/a> solve this. They sink straight to the bottom and stay there, so corydoras, loaches and L-number plecos can find them and feed in peace.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The pellets are made for fish that eat meat or a mix of meat and plants. They hold together in water, which keeps the tank cleaner. A good trick is to drop them in just after the lights go off, when bottom feeders are most active. It comes in 90 g and 250 g sizes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Best for:<\/strong> corydoras, loaches, and meat-eating plecos.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">7. StreamBiz Catfish Nuggets Soft Herbivore \u2013 Best for Plant-Eating Plecos<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Not all bottom feeders eat meat. Bristlenose plecos and many other plecos mostly eat algae and plant matter. <a href=\"https:\/\/bluviva.com\/product\/streambiz-catfish-nuggets-soft-herbivore\/\">StreamBiz Catfish Nuggets Soft Herbivore<\/a> are soft, plant-based nuggets that sink to the bottom and are easy for these fish to rasp at.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you have both a corydoras group and a bristlenose, you can use this alongside the Bottom-Feeder Pellets, so each fish gets the right kind of meal. It comes in two sizes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Best for:<\/strong> bristlenose plecos, other plant-eating plecos and otocinclus.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">8. StreamBiz Betta Natural Granules \u2013 Best for Bettas<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Bettas eat mostly insects and small creatures in the wild, so they need a meaty food. They also tend to feed at the surface, and they can be fussy. <a href=\"https:\/\/bluviva.com\/product\/streambiz-betta-natural-granules-40-g\/\">StreamBiz Betta Natural Granules<\/a> are made for them, with small granules that fit a betta&rsquo;s mouth.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Bettas are easy to overfeed, as they will often keep eating even when full. A few granules once or twice a day is enough. It comes in a 40 g tub, which lasts a long time with just one fish.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Best for:<\/strong> betta fish (Siamese fighting fish).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">9. StreamBiz Discus Colour and Angelfish Power Granules \u2013 Best for Larger Cichlids<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Discus and angelfish are larger, slower feeders that like their food to drift down in front of them. Bluviva stocks two foods made just for them: <a href=\"https:\/\/bluviva.com\/product\/streambiz-discus-colour-granules\/\">StreamBiz Discus Colour Granules<\/a> for bringing out discus colour, and <a href=\"https:\/\/bluviva.com\/product\/streambiz-angelfish-power-granules\/\">StreamBiz Angelfish Power Granules<\/a> for strong growth in angelfish.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For other cichlids, such as rams and many African species, the <a href=\"https:\/\/bluviva.com\/product\/streambiz-cichlid-colour-soft-granules\/\">StreamBiz Cichlid Colour Soft Granules<\/a> and <a href=\"https:\/\/bluviva.com\/product\/streambiz-cichlid-spirulina-soft-granules\/\">Cichlid Spirulina Soft Granules<\/a> are good choices. The soft texture is gentle on their mouths and easy to digest.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Best for:<\/strong> discus, angelfish, rams and other cichlids.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">10. StreamBiz Red Mosquito Larvae Paste \u2013 Best Protein Treat<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Every fish enjoys a treat, and a little variety helps keep them active and healthy. <a href=\"https:\/\/bluviva.com\/product\/streambiz-red-mosquito-larvae-paste\/\">StreamBiz Red Mosquito Larvae Paste<\/a> is made mainly from red mosquito larvae, with 50% protein. It is great for fish that love meaty foods, and for fry and small fish too.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">What makes it different is how you feed it. You press a small blob onto the glass or a piece of decor, and the fish pick at it, just like they would in nature. It is fun to watch and keeps shy fish interested. If you prefer a lighter option, <a href=\"https:\/\/bluviva.com\/product\/streambiz-artemia-paste\/\">StreamBiz Artemia Paste<\/a> works the same way. Both come in 70 g and 120 g sizes. Use them two or three times a week, not every day.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Best for:<\/strong> treats, fussy eaters, fry and small meat-eating fish.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">11. StreamBiz Pure Nature \u2013 Best Natural Food<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If you want to give your fish something closer to what they would find in the wild, <a href=\"https:\/\/bluviva.com\/product\/streambiz-pure-nature\/\">StreamBiz Pure Nature<\/a> is a good pick. It comes in four types in 100 ml tubs: Artemia, Artemia nauplii (baby brine shrimp), red mosquito larvae and white mosquito larvae.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Artemia nauplii are very small, so they are ideal for fry and tiny fish like chili rasboras. The mosquito larvae suit bettas, tetras and gouramis. Like the pastes, these are best as an extra food a few times a week, alongside a main daily granule.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Best for:<\/strong> adding variety, fry, and fish that love natural foods.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Build a Simple Feeding Plan<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">You do not need to make feeding complicated. A good plan for most community tanks has three parts: one main daily food, one food for the bottom, and one treat. Here is an easy example for a mixed tank with tetras, guppies and corydoras:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Every morning:<\/strong> a small pinch of Universal Granules or Tetra Natural Granules for the middle and top of the tank.<\/li>\n\n\n\n<li><strong>Every evening:<\/strong> a few Bottom-Feeder Pellets for the corydoras, dropped in after the lights go off.<\/li>\n\n\n\n<li><strong>Two or three times a week:<\/strong> swap one meal for Red Mosquito Larvae Paste or Pure Nature as a treat.<\/li>\n\n\n\n<li><strong>One day a week:<\/strong> skip feeding. This gives your fish time to clear their gut and gives your filter a break.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">If you are going away for a few days, an <a href=\"https:\/\/bluviva.com\/product-category\/accessories\/auto-feeders\/\">automatic fish feeder<\/a> like the Juwel SmartFeed can give out small, measured meals while you are gone, so nobody overfeeds by mistake.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Much and How Often to Feed<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The simplest rule is this: feed only what your fish can eat in about two minutes, once or twice a day. Watch them while they eat. If food is still floating around or lying on the bottom after a few minutes, you gave too much. Scoop it out with a net, and use a little less next time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Remember that a fish&rsquo;s stomach is tiny, roughly the size of its eye. It is much better to feed a small amount twice a day than one big meal. Young fish grow fast, so they can have small meals two or three times a day.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Overfeeding is the most common mistake in fishkeeping. Extra food rots and turns into ammonia, which can harm your fish. If you think you might be feeding too much, check your water with a simple <a href=\"https:\/\/bluviva.com\/product-category\/water-quality\/test-kits\/\">aquarium test kit<\/a>. Keeping your filter healthy with <a href=\"https:\/\/bluviva.com\/best-beneficial-bacteria-for-aquarium\/\">beneficial bacteria<\/a> also helps break down any waste that does build up.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Common Feeding Mistakes to Avoid<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Feeding too much.<\/strong> More food does not mean healthier fish. It usually means dirtier water.<\/li>\n\n\n\n<li><strong>Only using one food type.<\/strong> Floating food alone leaves bottom feeders hungry.<\/li>\n\n\n\n<li><strong>Keeping food open for too long.<\/strong> Once opened, fish food slowly loses its vitamins. Close the lid tightly, keep it somewhere cool and dry, and try to finish a tub within a few months.<\/li>\n\n\n\n<li><strong>Feeding human food.<\/strong> Bread, crisps and leftovers can upset a fish&rsquo;s stomach and pollute the tank.<\/li>\n\n\n\n<li><strong>Using food that is too big.<\/strong> If the granules do not fit in your fish&rsquo;s mouth, they will sink and rot. Choose small granules for small fish.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Tips for Picky Eaters<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Some fish, especially new ones, refuse food at first. This is normal. Give them a few days to settle in, keep the lights a little lower, and try a food with a strong smell, such as Immun Plus Granules or one of the pastes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You can also soak food in <a href=\"https:\/\/bluviva.com\/product\/seachem-garlicguard\/\">Seachem GarlicGuard<\/a> for a few minutes before feeding. Garlic has a strong scent that many fish find hard to ignore, and it can help bring back a fussy fish&rsquo;s appetite.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Best Fish Food<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th>Food<\/th><th>Type<\/th><th>Where it feeds<\/th><th>Protein<\/th><th>Sizes<\/th><th>Best for<\/th><\/tr><tr><td>StreamBiz Universal Granules<\/td><td>Granules<\/td><td>Middle, slow sinking<\/td><td>40%<\/td><td>40 g, 80 g<\/td><td>Mixed community tanks<\/td><\/tr><tr><td>StreamBiz Tetra Natural Granules<\/td><td>Granules<\/td><td>Middle and top, slow sinking<\/td><td>40%<\/td><td>40 g<\/td><td>Tetras and small shoaling fish<\/td><\/tr><tr><td>StreamBiz Guppy Granules Colour<\/td><td>Granules<\/td><td>Middle and top, slow sinking<\/td><td>38%<\/td><td>40 g<\/td><td>Guppies, mollies, platies<\/td><\/tr><tr><td>StreamBiz Immun Plus Granules<\/td><td>Granules<\/td><td>Middle, slow sinking<\/td><td>43%<\/td><td>80 g<\/td><td>New, stressed or picky fish<\/td><\/tr><tr><td>StreamBiz Spirulina Granules Indian Almond<\/td><td>Granules<\/td><td>Middle, slow sinking<\/td><td>42%<\/td><td>40 g, 80 g<\/td><td>Plant-loving fish, livebearers, cichlids<\/td><\/tr><tr><td>StreamBiz Bottom-Feeder Pellets<\/td><td>Pellets<\/td><td>Bottom, fast sinking<\/td><td>High protein<\/td><td>90 g, 250 g<\/td><td>Corydoras, loaches<\/td><\/tr><tr><td>StreamBiz Catfish Nuggets Soft Herbivore<\/td><td>Soft nuggets<\/td><td>Bottom<\/td><td>Plant-based<\/td><td>2 sizes<\/td><td>Bristlenose and plant-eating plecos<\/td><\/tr><tr><td>StreamBiz Betta Natural Granules<\/td><td>Granules<\/td><td>Top<\/td><td>Meat-rich<\/td><td>40 g<\/td><td>Bettas<\/td><\/tr><tr><td>StreamBiz Discus \/ Angelfish Granules<\/td><td>Granules<\/td><td>Middle<\/td><td>Species-specific<\/td><td>2 sizes<\/td><td>Discus and angelfish<\/td><\/tr><tr><td>StreamBiz Red Mosquito Larvae Paste<\/td><td>Paste<\/td><td>Stuck to glass or decor<\/td><td>50%<\/td><td>70 g, 120 g<\/td><td>Treats, fry, fussy eaters<\/td><\/tr><tr><td>StreamBiz Pure Nature<\/td><td>Natural food<\/td><td>Middle<\/td><td>Natural<\/td><td>100 ml<\/td><td>Variety, fry<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently Asked Questions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">What is the best fish food for tropical fish?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For most community tanks, the best fish food is a good-quality slow-sinking granule, such as StreamBiz Universal Granules. It suits fish that feed in the middle and top of the tank, contains around 40% protein, and has added vitamins. Add a sinking pellet if you keep bottom feeders, and give a treat food two or three times a week for variety.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Are granules better than flakes?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In many cases, yes. Granules hold together better in water, so less of the food breaks into dust that clouds the tank. They also sink slowly, so fish in the middle of the tank can feed easily. Flakes are fine for surface feeders, but granules are usually cleaner and easier to portion out.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How often should I feed tropical fish?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Feed adult tropical fish once or twice a day, giving only what they can finish in about two minutes. Young fish can have two or three small meals a day. Many fishkeepers also skip one day a week, which helps the fish digest their food and keeps the water cleaner.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Do bottom feeders need special food?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. Corydoras, loaches and plecos feed on the bottom and often miss out on food that floats or sinks slowly. Give them sinking pellets or nuggets, like StreamBiz Bottom-Feeder Pellets for meat eaters or Catfish Nuggets Soft Herbivore for plant eaters. Feeding just after the lights go off helps too.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can I feed my fish only one type of food?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You can, but it is not ideal. A single good-quality complete food will keep fish healthy, but adding one or two other foods gives them a wider range of nutrients and keeps them interested. A simple mix of a daily granule, a bottom food and a weekly treat works well for most tanks.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How long does fish food last once opened?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Once opened, fish food slowly loses its vitamins, especially if it gets warm or damp. Keep the lid closed tightly and store it somewhere cool and dry. It is best to buy a tub size you can finish within a few months, rather than a large tub that sits open for a year.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why are my fish not eating?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">New fish often refuse food for a day or two while they settle in. If older fish stop eating, check your water quality first, as high ammonia or nitrite can put fish off food. Try a food with a strong smell, such as Immun Plus Granules or a paste, or soak the food in GarlicGuard.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Final Thoughts<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Choosing the best fish food for your tropical fish does not have to be hard. Start with one good daily granule that matches your fish, add a sinking food for anything that lives on the bottom, and give a treat a few times a week. Feed small amounts, watch your fish eat, and remove anything left over.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Do that, and you will see the results within a few weeks: brighter colours, more active fish and cleaner water.
