Si vous comprenez ce que vous voyez et si vous vous y prenez t\u00f4t, la diff\u00e9rence est \u00e9norme.<\/p>\n\n
Ce tutoriel pr\u00e9sente les cinq maladies les plus fr\u00e9quentes chez les poissons d’aquarium<\/strong>: leurs caract\u00e9ristiques d’identification, les facteurs qui les provoquent et les moyens de traiter vos poissons en toute s\u00e9curit\u00e9 et avec succ\u00e8s, sans nuire \u00e0 vos plantes ou \u00e0 vos bact\u00e9ries b\u00e9n\u00e9fiques.<\/strong><\/p>\n\n Les poissons font partie d’un \u00e9cosyst\u00e8me ferm\u00e9<\/strong>. Contrairement \u00e0 ce qui se passe dans la nature, ils ne peuvent \u00e9chapper aux agents pathog\u00e8nes ou aux mauvaises conditions de l’eau. <\/p>\n\n Les maladies apparaissent g\u00e9n\u00e9ralement lorsque quelque chose affaiblit le syst\u00e8me immunitaire d’un poisson, par exemple :<\/p>\n\n Dans la plupart des aquariums, les bact\u00e9ries ou les parasites sont g\u00e9n\u00e9ralement pr\u00e9sents en tr\u00e8s faible quantit\u00e9. Les poissons en bonne sant\u00e9 y r\u00e9sistent. Les poissons stress\u00e9s n’y parviennent souvent pas. <\/strong><\/p>\n\n La maladie la plus connue et la plus fr\u00e9quente dans ce domaine est l’Ichthyophthirius multifiliis<\/strong>, commun\u00e9ment appel\u00e9e Whitespot ou Ich.<\/p>\n\n De minuscules grains blancs ressemblant \u00e0 du sel ou du sucre sont dispers\u00e9s sur les nageoires et le corps.<\/p>\n\n L’ichtyose s’attaque \u00e0 la fois \u00e0 la peau et aux branchies, ce qui la rend tr\u00e8s contagieuse et capable de g\u00eaner la respiration.<\/p>\n\n Traiter avec un m\u00e9dicament antiparasitaire sp\u00e9cifique tel que eSHa Exit<\/a><\/strong>. Une l\u00e9g\u00e8re augmentation de la temp\u00e9rature de l’eau, si les esp\u00e8ces le permettent, peut acc\u00e9l\u00e9rer le cycle de vie du parasite, permettant ainsi un traitement plus efficace. <\/p>\n\n Les nageoires sont d\u00e9chiquet\u00e9es, d\u00e9chir\u00e9es ou raccourcies.<\/strong> Les bords peuvent devenir blancs ou rouges.<\/p>\n\n Il s’agit g\u00e9n\u00e9ralement d’une infection bact\u00e9rienne<\/strong>, souvent due \u00e0 une mauvaise qualit\u00e9 de l’eau ou \u00e0 une blessure.<\/p>\n\n En l’absence de traitement, l’infection peut se propager vers la base de l’aileron et mettre la vie en danger<\/strong>.<\/p>\n\n Changez d’abord l’eau de 30 \u00e0 50 %<\/strong> et utilisez ensuite un m\u00e9dicament antibact\u00e9rien \u00e0 large spectre tel que eSHa 2000<\/a><\/strong>. Le charbon actif doit \u00eatre retir\u00e9 pendant le traitement. <\/p>\n\n Souvent confondu avec la tache blanche, le velours (Oodinium) est plus petit et plus dangereux.<\/p>\n\n La peau semble recouverte d’une fine poussi\u00e8re dor\u00e9e ou rouille.<\/strong> Le poisson peut para\u00eetre l\u00e9g\u00e8rement terne ou l\u00e9thargique.<\/p>\n\n Le velours cible \u00e9galement les branchies \u00e0 un stade pr\u00e9coce<\/strong>, ce qui peut nuire \u00e0 leur capacit\u00e9 \u00e0 respirer.<\/p>\n\n Utilisez un m\u00e9dicament antiparasitaire comme eSHa Exit<\/a><\/strong> et tamisez les lumi\u00e8res pendant le traitement, car le parasite d\u00e9pend en partie de la lumi\u00e8re.<\/p>\n\n Toutes les maladies ne sont pas visibles sur la peau. Les parasites internes sont des tueurs silencieux. <\/p>\n\n Les poissons peuvent devenir maigres bien qu’ils mangent normalement<\/strong>, et d\u00e9velopper un ventre creux ou enfonc\u00e9<\/strong> au fil du temps. Un signe pr\u00e9curseur tr\u00e8s courant est la pr\u00e9sence d’excr\u00e9ments longs, blancs et filandreux<\/strong>. <\/p>\n\n Chez les cichlid\u00e9s comme les discus et les poissons-anges<\/strong>, des maladies avanc\u00e9es peuvent provoquer la maladie du trou dans la t\u00eate<\/strong>, avec de petites d\u00e9pressions apparaissant sur la t\u00eate et le long de la ligne lat\u00e9rale.<\/p>\n\n La maladie du trou dans la t\u00eate est un processus multifactoriel<\/strong> \u00e9troitement li\u00e9 \u00e0 divers parasites protozoaires internes comme Hexamita (Spironucleus)<\/strong>. Cependant, le parasite en lui-m\u00eame n’est pas toujours la seule cause. <\/p>\n\n Les \u00e9pid\u00e9mies sont g\u00e9n\u00e9ralement li\u00e9es \u00e0<\/p>\n\n Certaines esp\u00e8ces de poissons peuvent \u00eatre porteuses d’une faible quantit\u00e9 de protozoaires Hexamita sans pr\u00e9senter de signes de la maladie. La maladie est contract\u00e9e lorsque les d\u00e9fenses immunologiques du poisson sont compromises. <\/p>\n\n Les infections internes progressent souvent lentement, mais la situation peut devenir grave. Les nutriments n’\u00e9tant plus absorb\u00e9s, le poisson s’affaiblit, ce qui rend sa gu\u00e9rison plus difficile. <\/p>\n\n D\u00e8s l’apparition de l\u00e9sions visibles au niveau de la t\u00eate, la maladie est d\u00e9j\u00e0 avanc\u00e9e : agir d\u00e8s le stade de la perte de poids et des selles anormales<\/strong> am\u00e9liore donc consid\u00e9rablement les taux de r\u00e9ussite.<\/p>\n\n Les infections internes peuvent s’aggraver rapidement si elles sont ignor\u00e9es.<\/strong> Un traitement pr\u00e9coce est essentiel.<\/p>\n\n Si les param\u00e8tres de l’eau sont parfaits (pas d’ammoniaque), mais que les poissons hal\u00e8tent \u00e0 la surface, soup\u00e7onnez des grippes branchiales.<\/p>\n\n Des branchies rouges ou enflamm\u00e9es. Un des opercules peut bouger plus que l’autre. <\/p>\n\n Si les poissons hal\u00e8tent mais que l’ammoniaque et le nitrite sont \u00e0 0 ppm<\/strong>, il est fort possible que des parasites tels que la douve des branchies soient pr\u00e9sents.<\/p>\n\n La r\u00e9duction de la consommation d’oxyg\u00e8ne due aux l\u00e9sions des branchies peut \u00eatre fatale si elle n’est pas trait\u00e9e<\/strong>.<\/p>\n\n Utiliser eSHa Gdex<\/a><\/strong>qui est efficace contre les douves branchiales et cutan\u00e9es et sans danger pour les crevettes.<\/p>\n\n Lorsque vous remarquez des sympt\u00f4mes, adoptez une approche calme et structur\u00e9e :<\/p>\n\n Commencez<\/strong> toujours par<\/strong> suspecter les pics d’ammoniaque et de nitrite<\/strong>. La qualit\u00e9 de l’eau peut parfois ressembler \u00e0 une maladie. <\/p>\n\n Un changement d’eau de 30 \u00e0 50 %<\/strong> r\u00e9duit le stress et am\u00e9liore l’efficacit\u00e9 des m\u00e9dicaments.<\/p>\n\n Les charbons actifs et les r\u00e9sines, qui peuvent absorber les m\u00e9dicaments, doivent \u00eatre \u00e9limin\u00e9s.<\/p>\n\n Vous devez suivre attentivement les instructions fournies par le fabricant. La plupart des traitements durent 3 jours cons\u00e9cutifs<\/strong>. <\/p>\n\n Surveillez les changements dans la respiration, la nage et la formation de l\u00e9sions. \u00c9vitez de nourrir lourdement les poissons pendant le traitement. <\/p>\n\n Certains m\u00e9dicaments, comme eSHa 2000<\/a> et eSHa Exit<\/a><\/strong>, sont con\u00e7us pour \u00eatre utilis\u00e9s ensemble. C’est utile lorsque les parasites provoquent des infections bact\u00e9riennes secondaires<\/strong>. <\/p>\n\n \u00c9vitez de m\u00e9langer des marques al\u00e9atoires sans v\u00e9rifier d’abord la compatibilit\u00e9.<\/p>\n\n Q : Dois-je mettre en quarantaine les poissons malades ?<\/strong> R :<\/strong> Si possible, oui. Un aquarium hospitalier<\/strong> emp\u00eache la propagation et permet un traitement plus contr\u00f4l\u00e9. Cependant, les maladies tr\u00e8s contagieuses comme l’ichtyose n\u00e9cessitent souvent le traitement de l’ensemble de l’aquarium<\/strong>. <\/p>\n\n Q : Ces m\u00e9dicaments sont-ils sans danger pour les plantes ?<\/strong> R :<\/strong> La plupart des traitements modernes sont sans danger pour les plantes s’ils sont utilis\u00e9s correctement<\/strong>. Lisez toujours l’\u00e9tiquette avant de proc\u00e9der au dosage. <\/p>\n\n Q : Mes poissons ont encore des taches apr\u00e8s 3 jours. Que dois-je faire ? <\/strong> R :<\/strong> Pour les taches blanches persistantes (surtout \u00e0 des temp\u00e9ratures plus basses), le cycle de vie du parasite est plus lent. Vous pouvez prolonger le traitement d’eSHa Exit de quelques jours jusqu’\u00e0 ce que les taches disparaissent. <\/p>\n\n Q : Les m\u00e9dicaments vont-ils tuer les bact\u00e9ries b\u00e9n\u00e9fiques ?<\/strong> R :<\/strong> Les traitements de qualit\u00e9 tels que eSHa 2000 et EXIT<\/strong> sont formul\u00e9s pour \u00e9pargner les bact\u00e9ries b\u00e9n\u00e9fiques du filtre<\/strong>, de sorte que vous n’avez g\u00e9n\u00e9ralement pas besoin de red\u00e9marrer votre cycle d’azote.<\/p>\n\n Q : Comment puis-je pr\u00e9venir les maladies des poissons ?<\/strong> R :<\/strong> Mettez les nouveaux poissons en quarantaine pendant 2 \u00e0 3 semaines<\/strong>; maintenez les param\u00e8tres de l’eau stables<\/strong>; effectuez des changements d’eau r\u00e9guliers ; donnez une alimentation vari\u00e9e et de haute qualit\u00e9<\/strong>; \u00e9vitez la surpopulation. Important : <\/strong>la pr\u00e9vention est toujours plus facile et moins co\u00fbteuse que le traitement.<\/p>\n\n La premi\u00e8re chose \u00e0 faire, et la plus importante, lorsque vous \u00e9levez des poissons, c’est d’observer. M\u00eame des changements mineurs peuvent \u00eatre des indicateurs majeurs. <\/p>\n\n Par cons\u00e9quent, la plupart des maladies courantes peuvent \u00eatre enti\u00e8rement prises en charge<\/strong> par un d\u00e9pistage pr\u00e9coce et un traitement opportun \u00e0 l’aide de m\u00e9dicaments appropri\u00e9s.<\/p>\n\n Les aquariums sains reposent sur la coh\u00e9rence, la stabilit\u00e9 et des actions \u00e9clair\u00e9es.<\/p>\n\n N’attendez pas qu’il soit trop tard.<\/strong> Si vous voyez un signe, traitez-le. Une r\u00e9action rapide avec le bon produit peut sauver l’ensemble de votre r\u00e9servoir. <\/p>\n\n Avis de non-responsabilit\u00e9 : lisez toujours attentivement l’\u00e9tiquette et les instructions relatives au produit avant de l’utiliser.<\/em><\/p>\n\n Les poissons peuvent tomber malades m\u00eame si leur aquarium est tr\u00e8s propre et bien rang\u00e9. En r\u00e8gle g\u00e9n\u00e9rale, les poissons ne sont pas vuln\u00e9rables aux maladies de fa\u00e7on soudaine. Les sympt\u00f4mes physiques et les changements de comportement commencent g\u00e9n\u00e9ralement de mani\u00e8re si subtile qu’il est facile de les manquer, surtout si vous \u00eates d\u00e9butant.
