I bought my baby ACF yesterday, and he is constantly climbing to the side of the tank outside the water and staying there. I know they are escape artists and I made sure the lid was secure, but he doesn't seem to be trying to escape, because of the fact that he stays in one position thats not too close to the top of the tank. I have been nudging him down with a net, because I began to get worried about dehydration and today I went out for a few hours, when I returned home he was on the side and appeared very dry, when I nudged him back in he seemed fine, but I'm getting worried about him dying if he continues to do this. Is this normal behavior for ACF adjusting to a new tank?
