Hi there, I just set up a 10 gal tank for my boyfriend as a gift and we're slowly but surely getting the hang of all of it. I do, however, have a question. When we were getting our fish, I specifically asked the (seemingly knowledgeable) employee that was helping us for fish that would be good singularly in a community tank, not a school. I didn't want to overcrowd the tank or risk reproduction. He recommended an angelfish, a pearl gourami, and a painted glass fish. Now, I don't need to be reminded how awful the dying of fish is. I learned that after I had already bought him (foolishly believing it was natural coloring) and I have complained and boycotted that particular pet store. But now I have learned that both the gourami and the glass fish need to be in schools! My question is this; can they be happy without a school? I want my fish to thrive and do well, but I can't put a school of each fish in a 10 gal tank!
