Can anyone please help me figure why my catfish had changed behaviour?
Its a Synodontis hybrid.
He's generally pretty sedate, but over the past couple of weeks he's started swimming up and down the front glass and round the tank.
Yesterday it was non stop ALL day and ALL night. He never stopped for breath! At one stage he had my 3 clown loaches doing synchronised loops with him!
I put in new decor yesterday and he seems to absolutely love it. Its a two part shipwreck and he's going in and out all the holes and seems like a kid in a sweet shop - so excited?!
Waters normal levels.
I'm hoping he's just deliriously happy

Thanks in advance for any help.
