well, it wasnt quite made clear enough, but if you plan on quarantining in only 2 setups, meaning 3 satanics in one and 2 ebenaui in the other, i dont think you're going the proper route. if you're planning on quarantining each animal on its own, it should be ok. here are my suggestions:
if you were planning to quarantine in groups, that setup just isnt right. part of the purpose is to be able to collect fecal samples with ease, as you can accomplish with the setup. but the other half of the quarantine is to have each animal separated for observation, so you can determine if any individual shows signs of illness. now if you have 3 satanics in one of those cages, and you find a fecal samples that seems suspect, how are you going to determine which animal it came from? so if you're deciding to house them in groups from the start, you might as well make the full setup and do something such as place moist paper towel on the floor to catch any feces that should drop. there simply is not enough room for more than a pair in that sized setup, and even that is pushing it if you plan on keeping them in there for any somewhat-significant amount of time.
second of all, do away with the saran wrap cover. i tried it when i started with satanics, and while it keeps the humidity up, it doesnt do any other good. you need circulating air which wont be accomplished with saran wrap blocking air flow. simply spray the cage/animals as needed (i recommend at least one good spray after lights out). the saran wrap will induce mold growth, which can open your animals up to new problems.
third of all, with so little to gather water from spraying (except of course the sides of the enclosure), your geckos wont have much to drink from. and i'd say from observation that hydration is a common problem with newly aquired uroplatus.
finally, give em more stuff to climb on. grab a few small sticks and it will increase the climbing space dramatically. you normally wont find these guys on the ground unless a) there isnt enough climbing space, b) the gecko is hunting, c) a female is looking for a spot to lay her eggs, or d) your gecko is ill. but with that little space, climbing areas will be crowded and your animals will not take to their new homes as easily.
so if you're going to house em together, scrap the critter keeper and get a minimum of a 15 gal for the trio, minimum 10 gal for the pair. plus, ebenaui (i've heard) are much bigger into hiding spots than satanics. but i guess youre already planning on that with the corkbark. and remember, simply cramming a small enclosure full of foliage isnt enough either.
good luck to both you and your geckos, hopefully good things will happen. they're wonderful animals. good first step in asking for critiques of your setups.
