I've got a long-nosed butterfly in QT at the moment, and a few days ago, he's started swimming strangely.
He'll swim the whole length of the tank from the left to the right, and then turn round and swim back but upside down?!?
Then he'll turn around and keep doing it - left to right, then right to left (upside down).
Is this normal??
He's eating fine etc.
