Mines acting odd, but not in a bad way I suppose. Took him a day, but he's swimming and skipping around the whole tankDon Henley in the background! Such an undervalued rock musician. Nice
When I added a seaweed blenny to my tank, he would perch on top of my MP40 or on top the return pipe and watch over the tank from up top. It took him a while to adjust to the tank and move in.
