Just wanted to add a little more information, the tank is 125 gallon long, there are 6 African cichlids and two bristle nose plate those that are babies, all of the African cichlids are still juvenile, We have done water test with the API test kit and all levels are perfect with everything. Four yellow labs and three have died so far, the fish in the photo has both cloudy eyes, and another one has one cloudy eye. The tank has been running for approximately one month. It has a 4x canister filter and a sponge filter, we lightly sprinkle in African Cichlid pellets two times a day, approximately a teaspoon each time. I gravel vac 25% water change once a week. We have eight other aquariums that have absolutely no issues. The tank in the photo is the one on the right that’s having the issues
