When I first got my frogs, I only had pellets as food. I didn't get any dried bloodworms until almost a year later. I usually put the pellets in the water and assumed they would eat them when they wanted. I watched a few times and they did the same thing -- spit them out. But that was the only thing I was feeding them and they are alive and well , so I assumed they must be eating them at some point... I actually don't think I have ever seen them eat anything. I do know that I have put the pellets on a dish and later I go look and they are gone. I think they eat them...
