havent read this thread for a while, It's been almost a year since I start having bichirs in my tank; the only bichirs that we could possibly get are senegals, albinos, endli, ornate, and longfinned; I've also noticed that they all have different characteristics, and they all cool pets to have; Ornate usually hunt at night, whereas endli always seems to have a big belly and grow really fast; Sens are true hunter in the tank, the fastest hunter to catch prey I say. Albinos are the most greedy bichirs I've known, always eat and eat, you could say is the garbage bin in the tank, so is the perfect choice to have if you dont wanna have leftover in your tank. Longfinned is similar with sens, though its funny to watch it swimming while swallowing its own beard, but not fast as sens.
These are just my observations till now, and if I hv to pick one, its going to be endli now. Watching it growing so fast in the tank and the whole body armour that they have are so heavily cool. By the way everybody hungry at night...so they all hunt when they light goes out
cheers
