One important thing, most small seiepcs of fish are schooling. Just keeping one or two doesn't work well. You want them in groups of around 6 or more.Then work on the idea that for small fish you need about a gallon for each fish. This ONLY works for small peacefull fish. Anything larger, allow more space.So while a 30gal tank could hold 30 small fish easily enough I would suggest sticking to maybe 5 types, but getting a decent number of each.Always get the biggest tank you can. You can allways keep a few small fish in a large tank, you cant keep lots of large fish in a small tank.Ianalso have pictus about 15 of em
