Hello. I recently made a thread on whether I should get a goldfish and give away my current fish. I was considering it because I was bored with the fish I have in this tank. Perhaps I have room one or two centerpiece fish? What do you guys think? Thanks! Here are some picture of the tank. I have eleven danios, nine corydoras, one albino rainbow shark, one albino bristlenose pleco, and a bunch of mystery snails.
