Axolotls need filtration that processes waste without creating strong current. Strong flow stresses benthic animals with external gill filaments, damages gill tissue, and can suppress feeding behavior over time. Sponge filters are the best default for most axolotl tanks because they produce gentle flow and excellent biological filtration. Canister filters fit larger or mul...

Axolotls absorb chemicals through gill filaments and permeable skin, which makes untreated tap water dangerous. Chlorine burns gill tissue on contact. Chloramine releases free ammonia when the chlorine-ammonia bond breaks during treatment. A dechlorinator that handles both is mandatory. Seachem Prime is the keeper-community default because it binds released ammonia in the ...

Cloudy water in an axolotl tank is not one problem with one fix. Milky white usually signals bacterial bloom from an uncycled or disrupted nitrogen cycle. Green water means an algae bloom from too much light. Brown or gray haze after maintenance is debris suspended from substrate. Test the water before reaching for a clarifier.

Axolotl ammonia burn is acute chemical injury caused by dissolved ammonia damaging gill epithelium and permeable skin, presenting as reddened gills, skin patches, surface gulping, and food refusal. First action: move the axolotl into clean dechlorinated water (tubbing) while you identify and fix the source. Recovery takes days to weeks depending on severity.

Axolotls are obligate carnivores that eat earthworms, sinking soft pellets, bloodworms, blackworms, brine shrimp, and daphnia. Nightcrawler earthworms are the gold-standard staple. Avoid feeder fish, mealworms, crickets, tubifex worms, raw terrestrial meat, and any plant matter. Hand-feeding or target-feeding with tongs is preferable to scattering food across the substrate...
