I got a foxface from the normal LFS and said he was doing great had him for a while. I got him he hide for the first day and the second day was out swimming around eating nori and hair algea. was out all day today and come home cant find him so figured he was sleeping in the rocks. Well came over to clean glass and he is stuck to the powerhead almost lifeless. I have a perc in the same tank and he is fine. I tested everything and its all normal. What could case him to be fine one day then almost dead right now. I dont know what to do it kinda poked the powerhead and he kinda floated away. Could it be maybe he is sleeping or is he on his way out? If he is should I take him out now or wait to see what hes like in the morning?
