gouramis
i keep them with live bearers, you might get one who likes to establish the tank as "his tank" but they are generally peacefull, i woul recomen pearl gouramis, moonlight, gold, opaline, or 3 spots, or my fav is the dwarf honey , these lil guys are so fun to watch very curious and are great at picking up scraps, and they dont ever bother uprooting plants, but they will occasionly take a nibble on some leaves, but i keep mine in a planted tank, they dont detroy plants, and are a pretty happy fish, let us know what you pick!!!
