Fat frogs.

Earthworms are just about the best thing you can give your frog and can be offered just as much as roaches which is my other favourite feeder.

Oh the same as turtles and hedgehogs then. But for fishes they get bloated with eating worms

In actuality feeding live earth worms doesn't cause bloat just full bellies. Feeding every other day is ok for for adult frogs.
They won't over eat. just feed what they will eat in 10 to 15 min and make sure all uneaten food is removed.

On the other hand freeze dried food will cause gas bloat and can be dangerous for both fish and frogs alike.

African Clawed frogs are very efficient animals and hold on to body fat (around the kidneys) very well. Which is why they can survive starvation conditions for a very long time.

As far as earthworms, I feed mine nightcrawlers often. Even my under 2" male frog gets a full nightcrawler now and then and he does just fine with it. If your frogs are becoming obese (which I doubt because a growing frog will turn energy into growth) then feed less often.

I would alternate between reptomin and nightcrawlers, toss in crickets once every few weeks for a live treat. I find throwing live crickets into the water is very stimulating for these frogs, they enjoy hunting.
