I bought a rack a month ago. Its a 5 shelf rack. Each shelf is is 5 1/2" in height. The rack came with 5 tubs. 3 of them are in good condition. The other two suck. What's unfortunate is that he original owner used sterilite tubs that are no longer available. I have been racking my brain trying to find the right size tubs.

Today I found one that might work. Its 5 1/4". There's about a 1/4" gap between the tub and the shelf above it. Do you guys think that is ok to use? I really don't see an adult or hatchling being able to get out of a 1/4" gap. My other usable tubs are snug and don't leave a gap at all. Do you guys think i'll be ok? Thanks.
