So I bought a clown about 3 weeks ago. he is happy, swimming EVERYWHERE all the time. He eats as best he can. I think it is hard for him to catch the flakes with the high water movement so I turn the power heads off for him. I started doing this recently. His body has become a little faded in sporadic areas. It doesn't appear to be a disease. He just looks a little faded. This happens with the damsels, their blue coloration fades, so I added a calcium supplement/ buffer and over night, they are back to brilliant blue. I'm having trouble keeping my ph up. its right at about 7.9-8. I'll be testing it again soon. I'm waiting on new test stuff. But I don't know what if anything is wrong with the clown. opinions please!!!
