I have a black onyx true percula clown who has been in my tank for several weeks. He has been happy and perfectly fine..... Until my water change yesterday. Tank is a 40 breeder with only 3 small fish ,live rock, and some corals. All other fish are doing fine and all coral looks good, except my pulsing zenia which looks like it got burnt.... I think it was too close to my bubble coral.... Anyways, after a 4 gallon water change yesterday, my clown started hanging out in one spot close to the bottom of the rock.... I got up to check on him about 4 am and he is now swimming, but appears to be blind? He is swimming low to the bottom, but is bumping into everything. What would cause this?? He is my favorite fish!! I do not know the water parameters as I don't have a test kit, but will get it checked as soon as the lfs opens today.
