I was using a 7" croc. Very nice but discontinued from the small selection of pet stores. So I found plastic dog bowls that are 5" for water and a wide 7" base. The fantastic thing is they are only $1.95 a piece instead of $8! I also use hides because my one girl is used to one and was in a cage before. The rack is also in my living room so there is more traffic than most people's reptile rooms.
