So I am looking for a good rack, I am going to purchase from boaphile, but I am confused with what rack to get, this rack is going to be for ball python hatchlings, would the rack that has tubs that are 14 inches long, 7 inches wide, and 4 inches high good? Or do I go for the 16 by 8 by 4? Their is a pretty big price difference, so if I could get away with the smaller one, that would be great.
