I agree with linda about the petshop setup. I never take petshop advice as far as im concerned they know nothing except how to sell animals. You are better off looking up forums such as this one for advice. I strongly recommend you seperate the snapper, baby turtles can grow very quickly and a snapper is very strong as a baby it can bite limbs off of other baby turtles. Yes it can get expensive but a couple good investments now will save you alot more in the future. Good luck!
