I have 3 whites tree frogs in a 30 gallon and they are about to move into a 55 till sometime after Christmas when their 75 will be ready.

Anyway my question is this. 2 of the frogs are extremely over weight the 3rd on is an average size. I feed them 20 large crickets every 3 days. Should I put Frogger ( the average weight frog) in the 55 and feed him his normal 5 or 6 large crickets every 3 days and give them fewer in the 30 till their size goes back down, or move them to the larger tank all together and feed them outside the tank for awhile? Or just feed them as usual and hope that they will move around more and loose the weight?

I will take pics when I get home.
