More than once now I have noticed this behavior with my pair. They seem to share the "Team work is dream work" mentality and I was wondering if anyone else has ever had anything like this happen. In what looks like an attempt to escape their enclosure (a large plastic koi pond for a couple more weeks until funds allow me to expand big time) one will brace itself on the ground you could say, while the other one will push off of it for leverage to climb the side. Their behavior clearly isn't fighting or aggressive but a teamwork attempt to get 1 of them out. As the one trying to climb out advances forward up the side, the other one will inch forward and hold it's ground, it's pretty creepy lol and I'm curious as to what "phase 2" would be once the 1st escaped...
