Why do fish.....

[cu0ngsayz]

I'm looking at my tank and I wonder why fish swim up and down against the glass or around in circles around the circulation pump

This is something I've always wondered.
I had a cytrocara morrii , blue dolphin hap, and he did this constantly, as well as our clown loaches and clown fish.
Maybe barametric pressure changes?

I have read that swimming up and down in a line is the sign of a happy fish opposed to swimmin n a straight line.... but up and down aginst the glass mabey they think there is some way to keep going.... i had a figure 8 puffer that did it so much it had wore its top lip thin and when he would go down it would jerk its upper lip up kinda felt bad but.. I DUNNO... kinda crazy

I don't know about all that, but I've heard several times that it was a social behavior

I think they are saying,(LOOK AT ME!) ( DON'T FORGET TO FEED ME!) or (AM I STILL YOUR FAVORITE?)
the circle swim is ( D%M THATs AN UGLY SHIRT!) ( GO CHANGE )

It's one of these or they're planning a prison break/suicide mission.
