I have two Grey Tree Frogs and once I put them together I was nervous one wouldn't get food. I now feed them with tweezers. it also has seemed to almost tame them a lil more they are less jumpy and wait for me to open the terrarium. I thought it would be a bit of a pain having to do this but I'm actually enjoying it a great deal. Makes feeding time more fun. If there is Frog by the glass bowl at feeding I will still use it for that one as long as a I know it sees them but I feed the other with the long tweezers.
