He also seems kind of...sad? He swims and eats, and I know he's a fish and not a puppy so I'm not expecting him to be too high energy. Something about him just seems kind of "blah".
I noticed this weird patch on his head right after I put him in his tank on Sunday after buying him. If you can tell from the pictures (I'm sorry they're so terrible!) It's kind of a white gray patch that looks a bit raised and lumpy. I'm wondering if it's a type of fungus of some sort?
Maybe that is contributing to his mood. I want him to be happy. Can anyone offer any input or advice as to what I should do for him? Please?
