yeah thats what is all strange about it. Phos-undetectable, No3-undetectable, PH-8.2, Mg, 1450, Ca 445, Alk 11, temp 79, other than the alk being a little high I can find NOTHING wrong with the water. Its weird though I noticed the other day that for about 20 min after the lights come on he looks normal, then goes black on his top half again....its really strange. Usually you think of it being the other way around. Hes in a 75 gal perfecto with only a few other fish so while not huge he should still have reasonable room. The blue hippo is the only fish that seems to show interest in him and they are usually swimming around together so I don't see that she is picking on him.
