An unsual catfish found in some Western Amazon tributaries, the Sleeper Dolphin Catfish is a specialized predator/parasite adapted for feeding on larger fish and dead animals in the wild. Their common name comes from the local name for the fish, “dormilon”, which reflects their nocturnal nature. Less of a predator than some relatives, they will readily accept prepared foods in the aquarium and tend to ignore tankmates too large to be eaten.
