I need some ideas for scavanger type catfish that comes from Northern Central America. This is for a Petenia Splendida biotope tank. I have done my research but can't seem to find anything that shares the same waters with bay snooks other that the blue channel cat, which gets way to large for my tastes. The main stipulation here is that in order not to become food the species needs to grow to at least 10" or so (yet not get larger than 20). Any thoughts?
