I do apologize if this has been asked..and I am sure it has... also posted on milksnake forum...thought I might get an answer here...sale ends today so Im hurried. sorry if this seems spammy

What is a good size tub for milks? I am planning on building my rack and would like to get my plastic while it is all on sale...(a local shop is selling the sterlite for 40% off).

Id like something that is not minimum, but average..not too much room, but I dont want to cramp them. Also - I see some with 6"H but is that enough head room?

Will be for nelsons and sins.

thank you!
