Another thought is...
Do you want action on the bottom? (Small loaches and cories are fun)
Action in the Mid waters (Some Tetra schools can be fun too)
Or action on the top? (Danios are a hoot to watch, lil' spaz fish, now with cool color variations)
Do you want a "centerpiece" fish (one maybe 2 Angels or a Small-ish Gourami, NOT both)
Not all of the above suggestions are "safe" tankmates, but merely ideas for various areas of your tank.
As someone else said, we need a lil more info from ya, Search through the "Profiles" section, find some fish that strike you as neat, and post them here....That will make it easier to give you suggestions *SUNSMILE*
