Ok so it has been a few days since my last post on here. My pleco is tripping me out! At first he looks sick then he looks fine... Can/Do High fin plecos fade in and out to blend in with substrate???? Bc one minute all his spots are dark then the next minute I go to look at him and some of his bady areas look faded almost to the point of I think he has some fungus. Now I'm worried I treated him and there was nothing wrong IDK, other then that My Ammonia is currently holding at 0 -.25 and my PH is holding at like 6.6 not where I really want it to be but at this point im just glad its holding and not dropping. Any suggestions on the pleco???
