Thanks for the help! Sorry, I should have been more clear. My grow up tanks are exactly like the one in the picture. So I just call them all Group A and Group B because they're in the same tank, but divided. I think I just call them tubs because all the snake are in tubs now so it's how my labeling system is worded.

Speaking of grow out tubs, I'm going to need some more! I can't wait till we move so I can finally build a rack system. I'm ready to get rid of the tanks!
