I've had good luck with lyretail anthias from TSM aquatics. They arrive fully quarantined and eating with gusto. I ordered 10 from them. One of them turned male in about 2 months. All eat mysis, flakes and pellets.
I highly recommend the Avast Plank fish feeder. Makes feeding flakes and other dry food mix a breeze. These fish like to be feed multiple times a day to thrive.
