I was using Omega One pellets, a few varieties, and a variety of frozen (Mostly Pro Salt and the odd Hakari) and just grocery store dried nori every so often.
The Rabbitfish and tang have figured out the Grazer. So everyone but the Anthias and Blackstripe wrasse (scared to see how long it lasts when she tries it) and Blenny are using the grazer. The Yellow Tang is using it but still prefers nibbling on the sunken pellets.

Even the wrasses leave it alone when the rabbit fish is at it. Wow....
Heres a couple of my obese wrasses chowing down.
