This is my first time having frog, well no I have always had African Dwarf frogs but this is my first time having Fire Belly Toads. They have a pretty cool home with plenty of plants and a great place to swim but they wont leave the floating log. Is something wrong? Do I have too much water? Are they not big swimmers?

They eat every day, I make sure the water is clean and the temp is good. Can anyone help me with this???
