So one of my gourami's are sick. I'm worried that its the stress of adding new fish to the tank but cant be sure. He's been lying on the gravel not really moving and breathing a lot faster than normal. I separated him from the other fish and gave him some fresh water to see if that helped but No avail. The temperature is fine in my tank its arond 78-79 degrees. He's not eating.If i put something near it he'll move away and then just plop back down to the bottom. I havent noticed anything strange with its colour at all its gills and fins look quite normal. No one is going near him and nipping him is this intestinal or fungal... sound like anything anyone has come across before?
