Two-toed amphiuma
Amphiuma means · also called Two-toed congo eel, Congo eel, Conger eel, Lamper eel, Ditch eel
A huge, eel-like aquatic salamander with a slick body, tiny two-toed limbs, and a powerful, snapping bite. It is hardy and long-lived but strong, secretive, and capable of inflicting a serious wound, making it strictly a specialist display animal and never a handling pet.

Part of the Aquatic amphibians
Fully or largely aquatic amphibians kept in cycled, well-filtered freshwater aquariums. They surface to breathe, prefer gentle current and hiding spots, and are not handling animals.
Habitat & space requirements
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.
Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.
Habitat & enclosure
House one animal alone in a large, securely covered aquatic tank: a 40 to 75 gallon (150 to 280 L) or larger setup with plenty of floor area and a tight, weighted lid, as they are immensely strong escape artists. Keep water shallow to moderate (they surface to breathe) with abundant cover such as PVC tubes, caves, and dense plants; these are intensely secretive animals that hide most of the day. Maintain temperate to warm-temperate water around 65 to 78 F (18 to 26 C). They tolerate a wide range but need clean, well-filtered, dechlorinated water. No UVB is required.
Substrate
Use a bare bottom for easy cleaning, or fine smooth sand if a natural look is preferred; avoid gravel that could be ingested. The priority is dense cover: layer in PVC pipes, large caves, driftwood, and robust plants so the animal can stay hidden, which greatly reduces stress and defensive behavior.
Equipment & setup
Run a strong, well-baffled filter (canister or large sponge) for excellent biological filtration, sized above the tank volume given their heavy waste. A reliable heater with a guard holds temperate temperatures. The most critical equipment is an absolutely secure, weighted, fully sealed lid, since amphiumas are powerful and routinely escape poorly covered tanks. Dim lighting suits their nocturnal nature.
Diet
Carnivorous ambush predator with a strong, snapping feeding response. Feed earthworms/nightcrawlers (an excellent staple), crayfish, whole fish, shrimp, and chunks of fish or other meaty foods, always offered with long tongs. Feed adults every 4 to 7 days and avoid overfeeding, as they become obese. Their bite is fast and powerful, so never hand-feed. Target-feed in the evening when they are active.
Behavior & temperament
Nocturnal, secretive, and largely sedentary, spending the day buried in cover and hunting at night by smell and touch. It is genuinely defensive and capable of a hard, lacerating bite with sharp jaws; large individuals can cause significant injury, and they thrash powerfully when restrained. This is emphatically not a handling animal. Move it only when necessary using a sturdy net or container, never bare hands, and keep fingers well clear during feeding. Keep strictly solo, as they are aggressive toward conspecifics.
Health
Generally hardy if water quality is maintained, but sensitive to ammonia, nitrite, and chlorine; their slimy skin makes them prone to bacterial and fungal infections (saprolegnia, red-leg) when water is poor or they are injured. Bite wounds from rough handling or tankmates can become infected. Avoid copper-based medications. Obesity from overfeeding is common. Provide stable, well-filtered water, ample cover to reduce stress, and quarantine wild-caught arrivals, which may carry parasites.
Tips, DIY & hacks
Treat this as a specialist, lifelong commitment: it is long-lived, large, and potentially injurious. Always use tongs for feeding and a net or bin to move the animal, never bare hands. Over-build the lid security with weights and clips. Provide generous hiding cover from day one to keep the animal calm and feeding. Most stock is wild-collected from the southeastern US, and some states regulate or restrict collection of native amphibians, so check local wildlife laws before acquiring. Note that Amphiuma is not currently on the federal Lacey Act injurious-salamander list, but related newt and siren genera are.
