I had to chuckle when you said you could see the reptomin in your albino.

I think that how much you feed them is different for each frog and their development. I only have adults and it is all I have ever had. At full size they eat 3 or so red wigglers each. Or one or even two floating blood worm tablets. Usually one.

I would start with giving a smaller worm to your frogs and see how they do. Like I said, they will tear it down smaller if they can't handle it. Judge it by seeing how far they get with the bulge you would usually give them. Now the frogs come right to the top to find more if they aren't full. Of course they might do that anyhow the porkers!
