Keep at it! I trained both a copperband and a mandarin goby to accept frozen and both are really hard to train.
Use brine shrimp, they seem to be the food most will take first. Turn off all pumps and get the water to stop moving then using a turkey baster or pipette squirt a little infront of the fish. Maybe have it land on some rock so they can pick at it. Some fish don't like food in the water column and prefer to pick off rock (thus the copperbands big snout). Once they recognize frozen brine as a food source they'll probably start taking from the water when you do regular feeding.
My mandarin actually hides in a spot each time I feed and I puff some food in the little rock cave just for him.
