I have a 10 gallon tank with 3 mollies, 1 dwarf gourami, and 1 cory. Does my cory need a school or will he be fine by himself. He isn't sulking like people say he would on his own. He eats, he swims, he follows my huge dwarf gourami named Overdose. What's up with that? I'm just worried that if I get more cories that there won't be enough food. If I did need a school I would only get 2 more. Would another dwarf gourami be good in my tank? 'Cause Overdose is really shy and only comes out when I feed him.
