I am either going to get some guppies or some sort of dwarf fish. I wanted to get these ryunkin (sp?) goldfish, but they get HUGE, so that's a no go! The guppies are pretty and they can live in small groups. And I think the other ones were dwarf gouramis? I don't remember the name, just what they look like. And possibly one of these small loaches I saw, he was funny! We thought he was dead (floating upside down in the corner) until we went closer and started to move a hand toward the tank, and he darted off lol! I think he was sunbathing. Now I will probably end up getting yet another tank and putting a betta in there lol! (I do have shelf room in the bedroom....LOL! My husband is going to kill me soon).
