Soak the freeze dried krill in garlic guard, then tie a piece of dental floss to one of the legs and bob in tank. When the fish sucks in the food the leg will break away. This worked for me when anything else didn't.
Tie a piece of dental floss around one of the legs of a krill and bob it in the tank. After a day or two he'll take them as soon as you drop them in the tank. Mine didn't eat for a week when i first got him and that worked.
