The tank is pretty heavily planted. I have a corallife 9Watt UV Steralizer, we run it after water changes over night. We thought that was doing something to the tank so we stopped using it everyday. After the fish showed signs of sickness we started using it again, running it every other day. We have it hooked up to the Fluval, just because we bought it new and know it runs good. The GPH I am not sure on, we are trying to find the GPH Regulator that reads it (I forgot what they are called at the moment LOL). None of our LFS carry one, we are going to order one from Dr. Fosters & Smith. I do want to say I don't think the Blue Ram with Pop-Eye was due to a injury from aggression, because both eyes were protruding from the start. And sad to say he is not looking to good and I think this could be his last day. And Maybe the Blue Paradise's lip was from someone biting him. The only thing was that he stayed at the top of the tank mostly or by himself, he never chased anyone and no one really ever bothered him. He even slept at the top of the tank. Also, I have not "Decided on things". it is just that I am asking what could be going wrong with my tank with Parasited, and bacteria and where this would be coming from and what to do. I understand that everyone has different views on how to stock a tank, but we don't have these fish in a 10 gallon tank. They are ina 75 Gallon palnted tank with MANY places to hide and get away. I respect everyones views on my decision on how to stock my tank, I was just wondering if you could help me on what to do on how to NOT have any more fish DIE!!! I am not worried about the Paradise Gourami anymore...because he is now gone. I am worried about my other fish having been in with sick fish. Or if maybe there is something in my tank that keeps recycling. I am trying the best that I can. and I will watch for any signs of injury with my other fish. Usually when we see agression we take them out of the tank. The problem is we don't see any and the Blue paradise was the only one with an injury. None of the other fish even have nips taken out of there fins, or any other signs of injury. They don't even get aggressive during feedings. I just don't know what to do, and am pretty much ready to give up on this big tank. We have other tanks that we have NO problems with and have never had disease. Even out dwarf puffer tank is doing great, and we bought them in bad shape and basically nursed them back to health.
