I have 8 cherry barbs with my 2 gold gourami in my 46 gallon, and they get along just fine. I have some vals in my tank that are starting to hang over the top of the tank water, and my male gold gourami loves to hang out there. Before the plants, he was always "on patrol" on the front glass, and wouldn't let the female come up front. They both love to eat some zucchini, and the female (you can see her in my avatar -- I think she is female, anyway) will eat about anything -- including nibbling at plants.....
