I am in the process of fixing up a new enclosure for Turbo, my sulcata. He's about 4 pounds. I am wondering something good to use for a water dish. I want it to be deep enough for him to sit in if he wants. I dont want to make it myself out of concrete because I will be putting it on a buried 5 gallon bucket with drain holes on the sides to try to help with the flooding season. I can't find a cheap used bird bath or anything that will work on Craigslist or anywear. I'm thinking about using some sort of bowl but I will have to glue some rocks on the bottom to make it so it's not too deep for him and to make the side slopes gradual enough/not so slick so he can get in/out easily. Years ago I once killed a lot of fish before I realized it was probably due to toxic glue I used I felt awful and I'm terrified to do the same to turbo. Any ideas for either a good bowl to use or some safe glues that would hold good in water that may possibly be at walmart or a local home improvement store?
