I got a 5 gallon hex for my dorm room a week ago. I ran it for a day and then added 3 corkscrew plants and a Black mystery snail. Its still cycling but I am wondering how many fish to get and what kinds. I was thinking of either neons or white clouds but I'm not sure if I can keep enough of them for them to be happy in the little tank. Would I beable to keep a small schaol in a 5 gallon?
