Glad you found them. XD But yeah I've had quite a few freak outs over my frogs hiding. Just the other day I swore my little blue White's disappeared, he wasn't in any of his usual sleeping spots and the tank is quite small and open, so I thought he had escaped. I took out all the accessories inside the tank and found him hiding under the paper towel! I was so relieved I thought he had really gotten out. D:

It happens, next time just wait for them to come out at night, I'm sure you'll see them then.
