Unfortunately no, I want to try and block off the water section but I fear if he gets over it he will not be getting back out. His hole he made is under the pothos the back right corner next to the water so he is always watching the fish and jumps in occasionally. I might need to go out and fget some sheet rock tomorrow and build up something for him to get out or try your method. But I still feel he will always dive to swim and get stuck
