So I'm new to ADFs as well. There is a care sheet on this site for ADFs that speaks to their needs. From what I've read, most people seem to be against pellets... And blood worms should only be a treat?

I give mine pellets since that's what they were eating at the pet shop. I put a little plate in a clear area of the aquarium and use a turkey baster. I put the pellets in the mouth of the baster (without water) and then put it in the water over the plate and slowly move it down to the plate. The pellets that fall out before reaching the plate, fall into the plate or near it (since I keep that area bear, it easy to pick up the pellets they don't eat with the baster).

Mentat recommended leaving the pellets for only 5 minutes to determine how much to give them (see how many they eat in those 5 minutes).
