I think they would, but 'out of sight' wouldn't benefit them at all. I personally don't have anything against springtails, but the T's seem to be annoyed by them if there are to many around. I think it has to do with them hopping around. Pin head crickets bug the hell out of the T's to big to eat them too.....
From what I've read(Dubious, I know.
), most sp. of isopods available locally will do fine at tropical temperatures, it's just that they can handle the cold as opposed to tropical isopods. Local isopod caging: Room temp. tub w or w/o lid, 2"soil, then 3-4" leaf litter, then a few pcs. of rotting wood/bark, light mist to keep it all from drying up to much every day or so. Feeding: Their substrate, occasional spoiled veges, cricket carcasses. Breeding: Let them do their thing. A dozen is more than sufficient to get a colony going. The babies are very hard to see, and may be there before you know it.
I'm trying to get a colony of "Spanish orange" isopods(can't recall the real name at the moment) going, but I haven't been able to get any yet. They are a more tropical variety. Cool looking little bugs too. I wanted them for the T's cages (Isopods don't seem to bother the T's at all. To mellow I suppose), but if they'll work in the viv that would be great.
