I purchased a one spot foxface for my frag tank Saturday afternoon. It got a little cold on the trip home and had almost no yellow on it at all. I slowly acclimated it and put it in the tank. I looked it up and found that it's not unnormal for a foxface to do so. Later that night, I looked in the tank and it was laying on its side on the bottom. Woke up the next morning and it was swimming around happy as could be. Last night I checked on it and it was in the corner with its tail on the bottom, sticking straight up. This morning, it's swimming around again as happy as can be and it is regaining it's color. My question is, do they normally sleep on the bottom like that?
