Hi, I got my YWG 4 days ago and off the bat he wasn't acting too normal. I thought he was just shy. But he just sits in his cave and the 2nd day I noticed he had some loose tissue on his lips. 3rd day, he had pale spots on his cheeks, and now today, his eyes are foggy and enlarged. I ordered some Melafix by API and its coming today. Is there anything I can do for him? I don't have a quarantine tank and everything else in my tank is fine. Parameters are ideal as well.
