I have such a problem! I have a 30 gallon tank that has been maturing for over 3 months prepared for a bimac (because octopets said that they can be kept nicely in a 25-55gallon tank), and now looking at all of these posts, you're saying that they need a 55 MINIMUM! Crap! Um, is it possible to keep a biareus in a 30? Oh, Lord! Please say yes! I can't afford a 55 and a filter for it! I'm only 16! NEED HELP!!!!!
