I have an Ornate Bichir. The scientific name is Polypterus ornatipinnis. It can get rather large, 18+ inches. They are carnivorous, and hunt for small fish, so small, slow-moving fish are not good tankmates. They don't see very well but finds most of its food by smell. They can be easily fed on "carnivour pellets" or "shrimp pellets" with the ocasional ghost shrimp as a treat. They need a large tank, mine is in a 75 gallon. It is sensative to light so a dim light level, plenty of dense planting with an open area and some root or rock caves make a nice environment. Good plants would be Amazon swords or large Anubias species. Good tankmates would be some semi-agressive fish, i.e. African Cichlids, mild mannered SA cichlids and the such. Basically tankmates that don't fit in it's mouth and leave it alone are good tankmates. You may want some top level fish to give more activity to the tank. All in all, it is an awesome oddball that can be a LONG time pet. Take good care of it and it will do well.
