I think i will take your advice and put some neons in and see how he reacts then go from there,thanks?I've had 2 gouramis and they both were very docile and could keep them with other fish so I think it really depends on the gourami I would start him out with a few neon tetras see how he does then go from there also by adding only a few fish at a time your not over loading the bio load and allowing your tank to slowly build up more good bacteria to combat all the new fish
