Hi. I have this pleco that I got from the LFS about 6 weeks ago and I think there is something wrong with his skin but I've spent weeks googling and searching forums and I just don't know, neither does the store. He's been this way since I bought him but this weird yellow colour seems to be spreading. He eats fine, swims around and chews his driftwood but I just can't seem to accept this might be normal and was hoping someone had advice? The people at the LFS couldn't figure it out and suggested I try dosing the tank with an anti fungal treatment and basically said see if that fixes it, if not come back and buy this multicure thing instead. I'll post my water parameters in the next comment but it's an established 55Gal with 2 Amazon sword plants, java moss, banana plant, 6 tetras, 3 danios, 3 MTS and a bamboo shrimp. Does anyone have ideas from the photos? It's not ICH and it's not fuzzy?
