there is 5 discus in there and 12 neons , 5 polkadot botias and around a dozen shrimp. I tried to add more but the new guys stressed the olderones out so i took them back. I might try to add more discus another time but im' still undecided, the fish are doing great now since the others are gone but i admit it does look empty, maybe ill get some rams or apistos or something .
