training angler to eat silversides

[marvinsae]

i've been doing some research on my anglerfish and i'm trying to train him to eat frozen silversides. i've been feeding him ghost shrimp but i've read that they shouldn't survive on ghost shrimp alone. also, it can get quite expensive. so i've tried wiggling some frozen silversides infront of his face for a few days when he hasn't eaten but he still won't take the bait. any suggestions?
