Goodness! lol. Looks like I will be going with the 3 tier adult rack lol. Thanks for that info! The males are already use to being in larger tanks than typically recommended for their size. My GFs adult male was in a 40gal terrarium and is now in a 32qt tub. My little male has been in a 20gal terrarium since being 87g. So, I think they will be ok in the bigger tubs with proper hides in them.
