I can attest to the fact that froglets will hide VERY well in a decently planted terrarium. I originally thought I could keep 4 young cobalt tincs, and then after a week I opted to do the shoebox thing. They're not at all expensive, and they keep your frogs healthier and happier, especially when they all get their own ration of flies. Not to mention imagine the stress on moving them twice, especially when you could take some sound advice and reduce stress on your frogs. hope this helps.
