I have a 29 gal. tank, with 5 lemon tetras, 1 red wag platty, 3 green corys, 1 common pleco (from my ignorant, start-up days)--he's about 3.5 inches long--2 small plecos, and 1 (I think he's still with us) kuhli loach. I cannot seem to keep albino corys, or red wag platties very well. Does anyone have any advice on what I can get as a "centerpiece" fish? Or am I too stocked right now? Maybe a snail? Thanks for any ideas! Katy
