I bought a new 55 gallon Tank and set it up. I know how to set up a tank because I have 40 tanks. It was now ready for fish so I put in 15 or so Demasoni Cichilids. About a week later I checked all the parameters and everything was good. The temperature is about 79 - 80 degrees and I have two large sponge filters in it plus a heater. Three weeks later all15 Demasoni were slowly dying. I checked the fish and they had nothing wrong with them. I had three other tanks of Demasoni and they are fine. By the way I have two Plecos in there that are still alive. Now I have a empty tank which needed to be scrubbed and new filters. I also put in the tank some salt and declor. Now my tank is ready for more fish. I put another 15 Demasoni in the tank, and about two weeks later all 15 slowly died. I still have the plecos and I put in two guppies which are living. I also changed the filters I now have a large water fall filter at one end and a large sponge filter at the other end.
Could it be to small a filter and to high a temp meaning not enough oxygen? The fish were not breathing heavy or acting strange in any way. What am I doing wrong I have never had this happen before.
