The Mormyrids lives in the demersal, potamodromous, freshwater environment.

Mormyrids are known for a few notable structural and physiological characteristics. They owe their apparent "stiffness" of body to their development, use of electrogenic sense. These fishes produce dipole moments, magnetic fields and can sense perturbations in the same. More

Mormyrids are distinguished by their snout which often is extended into a proboscis. The caudal peduncle serves as the site for a weak electrical organ used in orientation. More

mormyrids and eat them or mangle them. You should be able to keep medium sized mormyrids with African arowanas and African knife (Xenomystus). But the bigger knive sand arowanas will likely eat them. More

Mormyrids have a large brain-nearly equal in the body weight to brain weight ratio of humans. Most Mormyrids are nocturnal or crepuscular species. It must be noted that Mormyrids are poisoned by copper salts and so will react badly to most commercially available medications. More

mormyrids for their learning abilities and the fact that many species engage in apparent "play" behavior consisting of batting around small objects, including air bubbles, with the head. More

Mormyrids are freshwater electric fish that have specialized electric organs in their tail for sending signals. They also carry specialized electroreceptors on their skin that are used for electrolocation and social communication. More

Mormyrids have specialized electric organs for generating signals, and tuberous electroreceptors for receiving them. In electric communication, a variety of signals, varying in waveform and repetition rates can be generated for different social contexts. More

discharge (EOD) patterns of mormyrids and present new results on stereotyped signals and the mechanisms for signal generation in Brienomyrus brachyistius. In mormyrids, resting EOD rates are highly variable, ranging from 1-20 Hz. More
