I am working on my enclosure for my bullfrog... its 4' by 4' and the aquatic section is 3' by 3'... I used a dog swimming pool from petsmart... its about 6" deep... do I need to make a shallow end for him to be able to sit in with snoot above water or just a driftwood exit ramp to land. tonight I got the plants and the water section going... tomorrow I will fill in around the tub with earth and put sod and land plants in... then the grow lights above his pen. the enclosure will be about 2 feet tall that should be enough hight I think.
