I have two 90 gallon tanks that share the same filtration which is a 29 gallon sump. I have a mix of 17 africans from lake Malawi which are about 4 inches in average (some smaller and some bigger) in one and 11 Mwpimbwe Frontosas on the other which are about 4 inches also. I have notice that one of my Fronts, one of my Ice Blue Zebras and one of my Electric Blue Johannii have something white under one of there scales making it push outward. I just did a 25% water change and do a regular wc every week (25%). I also check my water parameters every week. My Ammonia is 0 nitrites 0 and Nitrates is about 15-20ppm. My GH and Kh I dont know. My PH is also 7.9. They dont seem to be acting different ie flashing, not eating sittin around not swimming. They seem to be normal. Can anyone help. Thanks.
