Right I added 2 Dwarf Frogs to my tank on Sunday. The went to the back of the tank probably to hide and seen them moving around to the front as the day went on. However since then I have not seen them since. To be fair I have not checked under my ornaments or anything like that but is it normal for them to be out of sight all the time. Do they not like to be on the move. 3 Days without a sighting seems strange.
