Well for the first time today i went to Price Chopper a local grocery store and bought a pound of frozen raw shrimp and let them thaw out and cut them up and fed them to my clan... all but the biggest one ate the non-live food? it was the same the other day with the frozen whole krill, he wanted nothing to do with anything that didnt swim? I have benn feeding for the last couple months one by one feeder so they would hit whatever hit the water? any suggestions?
