This is new today. I would have noticed if it was yesterday. All the other fish are behaving normally. No ammonia, no nitrite and 10 nitrate. Last water change was 5 days ago. No new additions to tank in the last few weeks.
He has had it hasn't he? Something probably quite major internally? I've been watching for 30 minutes and he can only swim like that with his head down.
