Does pay off I have finally gotten my radiant lionfish to take frozen food! He now will race up to the top of the tank to get krill, clam,squid and anything else.
Did the bay scallops work or something else? I have been busy for the past year attempting to trick a very sly leaf fish (Taenianotus triacanthus) into accepting frozen food. I have been successful getting it to recognize a turkey baster as the source of food, but it still only takes live ghost shrimp. On several occasions I have had him strike at a PE Shrimp (Piscine Energetics) only to change direction in mid strike when he realizes it is not live.
We have been having an enjoyable battle, in which he figures out my tricks within a few tries most of the time. I would like to hear any methods (your particular successful method especially!) in case I haven't really tried them all as it seems
