I feed mine raw shrimp I bought from grocery store. A little piece every time. He devours the shrimp in less than one minute. Sometimes I try other sea food such as chopped tilapia fish, squid, mussels, etc.
Some people feed their nems blood worms, black worms,,, we don't have to do that.
I know some petstore feed nems feeder fish (the freshwater ones)....We don't need to do that.
Anemones don't need to eat that often so feeding should not be a concern. Feed them the shrimp you buy from grocery store once/twice a month should be plenty to keep nems happy.
