I'm thinking about getting a bichir. I want to keep it with a gold flake pike cichlid and a green terror. In a 29 gallon for now and uprading them all the a 55gallon in 2-5months. Its going to be in a heavily planted tank. What should I feed it? the substrate is aquatic plant soil and pea gravel. I'm adding plant nutrients as well. It wont react bad to any of these things will it? does It need caves? cause I've seen tons of tanks w/o them. what should I feed them? Do i meat all requirments?
