Ok so I got a big RTCxTSN 2' (if not bigger) and the past few days every once in awhile when I go look at the tank he's standing almost on his head. not moving really any part of his body but his tail. and very little at that. Now I can walk around and look at him and he won't move. Untill I put my hand up to the glass then he moves and swims away like nothing happened. I have seen him do this twice and my G/f has seen it once. Is this something I should be worried about or is he just chillin' ?
seems to be a funny guy.
