Why do fish pace the glass?

[harris28]

My foxface spends his day running the front glass. It drives me nuts!!! I have had him for two years and most of the time he is glass running. What, if anything causes a fish to do that? He is the only one in my tank that does it.

He's simply expending energy. You should be happy you have such a healthy fsh.

If anyone can figure out why fish pick up certain habits---fame & fortune await you!

i always guessed it was to get out, swim more, not happy
its seems to be more common in new fish. my pacers stop after several months and just chill out

The new fish I just put in quarantine just spent 1 day darting back and forth at glass. I'm guessing he could see his reflection.

all my fish try to out race their reflection, they wont quit until they do...so they havent stopped yet

I have a yellow tang that acts like he is chasing away another tang. He will be swiming and looks over and sees his reflection( I guess ) and darts over to defend his corner. This tang is nuts for his corner.

Only my clowns do it. I think its for food purposes. They relate me to food.

A 75 gallon is small compared to the ocean. Think if you were in a small prison cell you might pace back and forth too. Lesley

my foxface did that against my powerhead almost like a underwater tredmill

my clown likes to do it to but gets tired and gets pushed back

Yeah my GSM will sit in front of the power head and try his heart out to touch it. That cracks me up!!
