Thanks guys. I want to move them out of the aquarium tank because I don't have a top cover. Ideally when the emerge from the water I would like them to be in the temporary tank while they finish absorbing their tails. I'll keep them in the temporary tank to grow some more and so I can keep an eye on their feeding. Also this will buy me some time to finish up their permanent home, a full live planted vivarium with misting system.

I was going to have a substrate of coco chunks topped with frog moss (not sphagnum). How big are these guys when they come out the water? Will they get lost in the moss? I was going to try and compact the moss as much as possible. I tried the paper towel substrate when I was isolating a pair of newly purchased RETF. I found that the paper towels dried up real quick. I won't have an automated misting system in this tank and I'll be only able to mist it twice a day. Once before I leave for work, 6am and when I return 5pm. I'm afraid the paper towels would be dry by then. Has anyone ever used those really absorbent towels they use for drying cars? We call them shammies in North America. They hold a ton of water, soft to the touch and won't likely dry out while I'm away at work. Since the tank is going to be temporary, I am aiming for fake plants right now.

As for feeding while in the temporary tank, I have started culturing crickets, however, my first set of pinheads might not be ready by the time they are ready to feed. How long does it take for the froglets to absorb their tails? In the meantime, I have a nice stable supply of fruit flies I've been culturing for a few months now. I'll give them that dusted with calcium and vitamins. Speaking of fruit flies, can these guys climb glass? I know crickets can't. I was planning to provide two methods of feeding, a shallow glass container I will dump the insects in, and also release some into the tank to get them used to hunting.

In terms of behavior, do they sleep during the day and become active at night like adults?

As of yesterday, a couple of them have front limbs. The others have the shape of the front limbs but they are still attached to their body. They haven't popped out yet.
