nymphs

over crowding will effect breeding significantly but with that amount, 5 gal as other members have stated will be fine. The secret is to create as much surface space as possible with egg crates. between 300-500 will be the max i would recommend keeping in 5 gal.

Thank you guys. So should I use a steritile tub or what? My room mate is nervous about this and I want to make sure they are 'secure'.

Sterilite brand is usually fine - avoid the 'rugged' style bins that have texture to them. The smallest of nymphs can grip even fine texture on a bin, so feel the inside-surface before purchasing to make sure its completely smooth.

how are they kept heated in a tub? Do you need to cut the top and place a metal grid across?
