I have on Pink Kissing Guoarmi in a tank with 3 small comets. I know that Guoarmis are tropical fish and that goldfish arent, but they all seem to be healthy. The temp of the tank is usually around 76-78 degrees. My guoarmi doesnt seem to be bothered by the temperature and neither do my comets. I put the pink kisser in the tank with the comets because he was harassing all my other fish and they were the only fishies that were just as fast as he. He's no longer a bully and in fact he acts like he's just another comet himself. Should I just leave him in the tank?? Can tropical fish and goldies survive together???? Can they tolerate a temperature overlap??

The ideal temp for gouramis is 73 to 81F. They should be kept with other laberynth fish of the same size. I guess the gourami will eventually become a bully again... goldfish are peaceful fish. The comets are fast but they will eventually stress out due to the gourami.
