Does anyone have v-70 tubs? When in a rack, are you able to see what's happening inside or do you always have to pull them out to peek? Does anyone use v-70s with reptile basics racks? I'm thinking I may go this route but my concerns are: 1. that I will not be able to see my snakes anymore without pulling out the tubs and 2. I'll have to drill the tubs for ventilation. Not the worst thing, but if I'm buying higher quality tubs I don't like the idea of having to drill them to bits. Thanks guys!
