Right, I'd only consider a Pearl Gourami if I didn't do the molly tank. I'm open to any other suggestions on peaceful, larger fish that are somewhat hardy and not likely to terrorize my smaller fish. I guess I could also do another small schooling fish like cherry barbs.Pearl gouramis are very peaceful, but they won't eat many more mollie fry than your current fish, their mouths are quite small ...& they're gentle almost always, except in a very small tank.
