fish acting wierd?

[YE||0W TA|\|G]

I have a few fish in a QT and they have been swimming fine for over a week and now they are very very active, swimming really fast. there not breathing hard and show no signs of any parasites or stress? Anyone ever experience this?

Maybe the walls are closing in on them. Stir crazy.

You ever been to jail before?
