I noticed that one of my crays has an infection on one of his eyes. He has been out moving around the tank, which is odd because he usually sits in his cave. I know that this was caused by an increase in tank temperature (summers coming...im working on cooling the tank). But I want to know if I should quarantine him into a cooler tank in the meantime? (I have another cray in the tank with him) What else can I do to help him?
