Anything really will work. I prefer to use a ten gallon or larger tank for those two. I put a half inch of moist spaghnum moss into the bottom and mist once a week or whatever it takes to keep the moss moist. Then once they hatch I leave them in there until about L3.
I also use jars sometimes...this way when the ooth hatches, you can easily put the jar into something bigger. Unless that you hatch it in is the home for the nymphs anyway...
By L3 you might have 20 if you're lucky. At least thats what I end up with when leaving them all together. Usually less. That's fine for me because it's an easy number to care for.
