I just looked at Admiral Finns today, and what do I see? A loose scale. I don't see how he could've injured himself, as I've never had any issues with that before [aside from when he ripped his fins on the plastic plant, that I removed..]
Is there anything to worry about? I'll keep watching him to see if anything else happens, but it just looks loose, it's not red or showing any sign of other injury. He seems perfectly happy, as he built a bubblenest while I was in class [again]. If there's anything I can do, and anyone out there knows, please tell me :) [I read that a reason for a loose or lost scale could be dying of a fungal infection or that he's just old.. but I have no idea how old he really is..]
