Fish food is one of the most important parts of aquarium care, as it contains the necessary nutrients your fish needs to grow, stay active, and show off those beautiful colours.

Whether you’ve got goldfish, shrimp, tropical fish, or bottom feeders, giving them the right food keeps them healthy and helps your tank stay balanced and clean.

There are loads of different fish foods out there, and they’re all made for different kinds of eaters. Flakes and floating pellets are perfect for surface feeders like guppies and mollies.

If you’ve got bottom dwellers like catfish or shrimp, go for sinking wafers or granules like the StreamBiz Catfish Nuggets (they come in herbivore or carnivore versions), or Discus Colour Granules if you want to bring out brighter colours.

Paste foods like Artemia Paste or Red Mosquito Larvae Paste are packed with nutrients and great for picky or slow eaters. You can also add foods like Azoo Vitamins Plus or GarlicGuard to support immunity, boost appetite, and keep your fish in top shape.

When picking your fish food, think about a few things: what kind of fish you have, where in the tank they like to eat (top, middle, or bottom), and what kind of diet they need—herbivore, omnivore, or carnivore. Look out for foods with high-quality ingredients like spirulina, whole fish meal, or insect protein. These are easier to digest and won’t cloud the water. Sinking granules are a go-to for catfish and shrimp, while floating or slow-sinking options are better for mid- or top-level swimmers.

Feed your fish once or twice a day; just enough for them to finish in under two minutes. If there’s food left after that, scoop it out to keep the water clean. Rotating different food types is a smart way to make sure they’re getting a well-rounded diet.

Feeding isn’t just about keeping them full. It’s key to helping them thrive, stay colourful, and live long, healthy lives. Check out our full range of fish food to find the right match for your tank.

FAQs About Aquarium Fish Food

(1) What is the best food for fish? 

It really depends on what kind of fish you have. Carnivores do best with high-protein pellets, while herbivores need food that’s mostly plant-based. Brands like StreamBiz offer species-specific options for fish like cichlids, discus, and angelfish; great for growth and colour.

(2) What food makes fish grow faster?

Look for high-protein food made with quality ingredients. Pellets with 40–50% protein are ideal for meat-eating fish, and vitamin-enriched flakes help support general development. Feeding smaller portions more often throughout the day (instead of one big meal) also helps them absorb nutrients better.

(3) What should I not feed my fish?

Skip the bread, rice, or table scraps. They don’t offer the right nutrition and can mess with your fish’s digestion. Also, avoid expired food or anything that’s been stored somewhere damp. And unless you’re sure of the source, steer clear of live food; it can carry diseases into your tank.

(4) When’s the best time to feed fish?

Daytime is best, especially in the morning and evening when fish are most active. They also digest food better in warm water, so avoid late-night feeding. Leftover food just breaks down and messes up your water quality overnight.

(5) How much food should I give my fish?

A good rule of thumb: only feed what they can eat in 2–3 minutes. For adult fish, that’s usually around 1–2% of their body weight per day. Younger fish need a bit more: 3–5%. Watch their activity and adjust based on how much they’re eating and the water temperature.

(6) What can I feed fish if I run out of food?

You’ve got a few short-term options. Blanched veggies like peas or spinach work for herbivores, and a tiny bit of cooked egg yolk can help keep others going for a day or two. But these are just temporary fixes. Proper fish food is still the best for long-term health.

(7) How do I know if I’m overfeeding?

 If the water looks cloudy, there’s food sitting at the bottom after a few minutes, or your fish seem sluggish or bloated, you’ve probably overfed. Cut back right away and check your water quality. Too much food can lead to bigger problems down the line.
