Ok so now im wondering... if im getting a 27x 6quartt rack and.... a 7x 42quart rack i think this will be a problem as far as the in between hatchling and adult sizes.

1.0 mojave ~150g
0.1 lesserbee (incoming)
1.0 lesser ~450-550g
0.1 pastel ~250g
1.0 spider ~1300g (incoming when weather permits)

for example i think my female pastel would be too big for a 6qt and a 42qt will be too roomy?
or is there a chance ill be able to put a smaller amount of larger tubs in the hatchling rack? like 18x 15qt tubs.. i imagine not.. >.<

PLEASE PLEASE any input will be greatly appreciated
