Who Gives A Fish Forums

If it's fin rot, you might need meds. But try the natural fixes first. Almond leaves, clean water, and stress reduction usually do the trick.

My guy had this and it was just stress from a recent move. Gave him time and he bounced back. Sometimes it's just a weird vibe.

How's his behavior? If he's still active and eating, it's probably not too serious. Just keep the water pristine.
