I'm sitting here watching Napoleon repeatedly climb up onto his floating dock, crawl to the edge and get tipped off. I think he may be just slightly too heavy for it.
I work in a frame shop, so I have access to plexiglass and i do have the ability to bend it. I'm thinking about making an L shape and using aquarium silicone to attach it to the bottom of the dock, so it would still float, but would stay perpendicular to the wall. My question is: is plain old plexiglass safe to have in the tank? Does anyone have other ideas?
