As far as pellets by them self NO but i wouldn't give up if your haveing difficulty try stuffing a few pellets into a night crawler that works for me when feeding large spiny eels
My 23" fire eel is super picky. He will not eat anything but live tubifex worms. Believe me, I've tried ! He did however try some live ghost shrimp once, but was turned off from then on. I love my eel.
