I have a beautiful PB that I have had for about 3 weeks. Destroys Nori when I place it in the tank. My concern is that when I feed Mysis, pellets, flakes it only barely eats at all. Will the PB be fine on just Nori and algae in the tank or does anyone have any other suggestions. In the past I have had a purple, orange shoulder, yellow, and I have been able to get them to eat anything I put in the tank. Any suggestions or advice is greatly appreciated.
