Polypterus;1464244; said:IMO the coloration on this fish is physiologic and not Morphologic. It is not terribly uncommon for a gar to have this Red brown coloration to them. I have a Shortnosed that was much like this one when it was smaller. Not so much now that it has grown.
in that case, a change in enviroment should return the fish back to it's normal colours, no? or does age simply put it right. what causes the red colouration?
