I have a 2 year old axo we just recently bought. When we got her she had one gill that has a white tip. She is eating and going to the bathroom and her water levels and temp are great. However she looks lopsided as one side of her gills all look long and feathery and the other side not quite as long at all. I do know she came from a exotic specialty store and was in a tank with about 20 other axo's. Any idea what this could be or if I should be worried?
