I love our new aquarium and our little fishies but I'm afraid we may have gotten ourselves in over our heads... we have a 20 gal tank and a penguin 150. Currently we have 5 neon tetras, 3 hatchetfish, 1 black molly and 1 cory catfish. I posted a help question in the freshwater forum because I think we may have too many fish, already, in our 20 gal tank and I just learned that the cory needs at least 2 buddies to be happy and the hatchetfish might need a school of 6 rather than just 3 - ? So I'm wondering if we should find new homes for some in order to give the remaining ones a better environment... Thoughts and ideas welcome!
