i feed my 4 inch senegalus bichirs brine shrimp and sinking pellets. the temp could range from 70 to 78 degrees. They are a slender and ETREMELY hardy fish. they are not very aggresive so you can keep them with basicly any fish that is 1 or 2 inches bigger then them exept for very aggresive tankmates like large cichlids. hopes it helps. check google for more info!
Food: Frozen is good, bloodworms, brine shrimp, you can also feed small pieces of market shrimp, earth worms, when they get big enough hikari sinking carnivore and massive pellets
Temperature: 78-84 degrees farenheit, they do well in relatively warm water
Structure: Basic Driftwood/plants etc
Compatible fish: Virtually anything that won't eat them and anything they can't fit in their mouth
actually, among all freshwater fishes, bichirs are the hardiest and the easiest fish to keep in a home tank even for a newbie. It is always better if you can train them to accept pellets which contains sufficient nutrition, instead of live food since young. If you have enough tank size for them, they are better be housed within their own species. The are stickies in this forum which will give you ideas on each maximum sizes.
LOL you are posting in the Polypterus section. I can assure you that at least 60% of the active users here have experience with them since they are the most common bichir available and to a certain extent, a beginner bichir.
Read up on the Bible of Polypterids.
