like u, i hav a community tank with small fish such as cherry barbs and neon tetras. it also has slightly larger fish such as platys and dwarf gouramis. i added a blue ram to the tank a few weeks ago, hes doing fine, is very peaceful and the other fish don't trouble him at all. so i would say, go ahead and try it! rams do have long, delicate fins though, so if you do have fish like tiger barbs who tend to fin-nip then maybe u should think twice.
