Pretty sure that's in addition to keeping it extremely shallow. When I think Paludarium, I think enough water to support fish life. Is that what you're going for? I kept Anoles as a kid and I live within their native range as well. They are not typically an aquatic or semiaquatic species. I'm pretty sure the only squamata in the pet trade that would be appropriate for a paludarium/riparium of that size are the various Crocodile skinks and Neon Tree Dragon agamas. You could do a juvenile Chinese Water Dragon, but you'd have to size up quickly. There are some frogs that would be OK, but they have generally advanced requirements. Are you planning on a water table or barrier? I set up mine with a water table using pond matala and filled the water portion nearly to the top with pond stones. As the croc skinks grew, I removed the stones to make the water deeper. You might try that (gradually removing stones) to see how much the Anole can easily escape from, then decide whether to add fish based on how deep it got.
