I used to feed frozen krill and shrimp soaked in garlic and zoe for extra nutrition, with the occasional (1-2 month) live feeder crayfish or fiddler crab, BUT recently I have found my peacock's weakness: GARLIC SCALLOPS! the farm raised ones from the grocery are nice and small, and Boris goes absolutely crazy for them as soon as it hits the water! normally he wont venture out too far when i feed krill or shrimp, and it takes some effort to make him take them BUT the scallops he will zoom around the tank and come all the way to the front glassand rip it off the skewer! However,, my friends Ciliata did not like the garlic scallops, so I guesss it is a matter of personal preference....
