So I've had a pair of clownfish for over a month, last week I decided to change where my gyre was positioned to have some better flow in the tank, one of the clownfish is swimming all over the tank and hanging out with a blue hippo tang, the other one has been swimming on one corner like of its struggling to swim, attached is a video of it, should I worry about him? Or is this another case of weird clownfish behavior.
