Mormyrids are distinguished by their snout which often is extended into a proboscis. The caudal penuncle serves as the site for a weak electrical organ used in orientation. Using this organ, Mormyrids are able to communicate with each other, find prey, and detect predators is murky waters or at night. Mormyrids have a large brain-nearly equal in the body weight to brain weight ratio of humans. Most Mormyrids are nocturnal or crepuscular species.

S: bottom, middle
TANK: A 30" (76 cm) or 25-30 gallon (95-114 L) is sufficient, although larger tanks are required for individuals exceeding 6ä (15 cm) in length. The tank should be well-planted and muted lighting should be used. Provide overturned flower pots, pipes, caves, or tubes for each fish to serve as a retreat. Use fine gravel or sand as a substrate. Furnish the tank with wood and rocks.
WATER: pH 6-7.2 (6.7), 3-12 dH (7), 73-82¡F (23-28¡C)
SB: The Elephant Nose is peaceful with other community fish, but territorial with others of its own species. Do not combine with aggressive species (Cichlids) for the Elephant Nose may not be able to compete for food. Do not keep in pairs as the weaker fish may be harassed. The Elephant Nose can be combined in groups of three or more because the aggression is dispersed. A nocturnal species.
