they prefer sinking ones they'e having hard time to get pellets on top of aquarium.

Not really. Like Tony said they just like to eat, period. Feeding them sinking pellets just increases the chance to ingest substrate and creates more of a mess if uneaten. I actually have my frogs "trained" to take food from my hands if I hover it above the water. Its actually pretty amazing how far they can jump out of the water and snatch food, they're quite accurate too!

ive trained my frogs to eat out of my fingers too, it makes it easier to monitor food intake and that all of them are eating well too. :-)
