Well I have mine in a tank of fresh water with a stick for them to swim with. I feed them baby fish food and they love it. They don't need lad other than a stick or two till their front legs pop out. Some day so take them out o the water then but I have been letting nature take its course and letting them climb out on there own I just moved them to a separate tank with mostly land and shallower water once their front legs popped out.
Hope this helps. I am still learning so I will post more a I learn it.
