FYI to anyone having difficulty with a finicky Regal Angel, I've tried feeding a number of things to a stubborn Regal Angel with little success -Spectrum Flakes, Spectrum Finicky Fish Formula, Angel Food, Prime Reef, Nori. Fortunately, a friend suggested Cilantro and it has proven to be the most irresistable food to the Angel so far. Just thought I would share this info.
