I finally convinced my brother to clean out his lizard tank (about 40 gallons) and fill it water that's been empty for going on maybe 6+ years now.. unfortunately the middle was bowed out by about 1/4th of an inch compared to the sides and was obviously not fit to house fish. So off to the fish store we went to get a proper tank, filter, and substrate. We picked up a 30 gallon that is 36in long and 12in deep (can't remember how tall) and some eco-complete substrate to get things rolling now the question is.. what can I put in it?! I have never had a tank this big and have no idea what I can put in it. I would like a big community tank and my brother likes bala sharks but I know they get far too big and turned him onto rainbow sharks and that's pretty much as far as we got. I wouldn't mind some schooling fish like my green tetras but I don't want that to be it. The tank had quick start bacteria in it which cycled my 10 gallon in about a week, if the 30 plays out the same it should be ready by next Friday. I will have a light and heater a few days after that which gives me some time to plan.
