for the past couple of months I've been working on my saltwater tank(which is finally done, well with the exceptions of corals) and I haven't done much with my 20 gal. at all. currently the only fish I have in there are 2 glow-fish, 2 dwarf gouramies and of course a small bottom feeder. anyways, can some one give me some suggestions of interesting and colorful fish I could add? thanks!
