I'll have had them for 5 days, today. The fruit flies climb out of anything I put them in. I've left fruit flies in their tank with them in the hopes he would eat, but he isn't. He wouldn't even go after the food yesterday. I'm afraid that he will probably be dead when I get home. The other toadlet seems to be doing fine though. Their tank has reptile dirt with a very shallow pond and a decoration for them to hide under, which toadlet B, the one who isn't eating, has dug himself a nice hole under.
