Unreadable as ever. For almost a week he would come up to the play corner when he would see me. When I put my hand in the tank he would let me pet him and sometimes even come up and rub on my finger. The next week (ie THIS week), he stays on the side of the tank and wants nothing to do with me. I tried to get a video of him voluntarily rubbing on my finger but he has been in his, leave me alone, mode ever since I made the attempt. I don't think the camera is at fault for the behavior shifts but am not totally ruling it out.
He is eating slightly less and is getting picky. Now I have to offer a live crab every other day. After he catches and eats the crab, he will also take a small piece of shrimp. If the shrimp is offered first, he pushes it away. On the day after the live crab feast, he will take half a medium shrimp with gusto.
