We moved the froglets into the 40 gal tank last night.
The thinnest, darkest one was the last to transform, and is now much smaller than the other two, who are growing at an alarming rate and getting fatter by the hour! But they are all doing well, it seems, and really love their new home.
I do have to turn the filter off in order to feed them.
They are pretty smart, and have already figured out that I put the majority of their food in the terra cotta dish. I was worried at first when they didn't seem to be able to find food unless they accidentally landed on top of it!
