Possible fighting? New behavior
So I recently moved my two sliders into a 55 gallon tank. They just did something I have never seen them do before. It kind of looked like they were fighting. They were nose to nose and one would shake his two front feet really fast and then the other would shake his. Is this something I need to worry about? I have never seen them do it and I would think that now they have plenty of room so there isn't anything to fight over. One of the turtles is a little more aggressive but only towards the fish and shrimps but they are there for food. I just don't want him to be a bully.
