Hmm, hello and welcome!
Hmm, try to feed only every other day or every 2 days. You don't want an obese frog(well fatter than they are supposed to be). Try putting black background on both side(left, right) and the back. It relieves stress on the frogs. The more climbing area you give them the better, these frogs love to climb. They will love to hide in a tall area. ;]

Your frogs look very healthy and adorable. Best of luck
