Any tricks to get a Manderin to eat anything?

im training my scooter blenny as we speak. i heard live brine in a baster with frozen foods, slowly switching to only frozen. i cant seem to find brine eggs around here so i just use munnids and small anphipods. has been about a week now and i see her picking the odd frozen brine/pellet. idk how much shes actually eating yet tho? good luck!
