I'd agreed with wannaarro on this, based on experience. I've bought 2 BGK and I have put them in a 20gallon tank. I put some driftwood, they seem peaceful enough but the next day one of my BGK is dead and the other one has an injured tail.
Bichirs are compatible with BGK. or try the green or gold severum, they are good tankmates, but the problem with severums, same with the BGK they are aggressive with their own kind.
