Hoping someone can help me-please? Ok- I have a 110 gallon tank, 2 aqueon quiteflow 55/75 filters, heater, submersible UV sterilization light/pump and plenty of aeration. In my tank I have 2 blood parrots, 2 jeweled cichlids and 1 african yellow cichlid. I had 2 african yellows but about a month...
