Elephant noses can grow to 9 inches, and need a fairly large tank, since they grow to 9 inches. They like to be in groups of at least 3-5 fish and they prefer subdued lighting (you can achieve this by putting cardboard at intervals between the hood and the splash guard. They like planted tanks, with plenty of hiding spots (upturned flowerpots, caves, pipes, etc.) They prefer a pH of around 6-7.2, but aren't too picky as long as it remains constant (doesn't change too much). It can be kept with other community fish, but shouldn't be kept with cichlids. For food, they'll eat many live foods such as Tubifex, eathworms, brine shrimp, and Artemia, freeze-dried and frozen foods, and some will take flakes.
Also, it uses a small electrical organ to find food, and shouldn't be kept with different fish that use one too.
