I'm continuing feeding and it's hard to tell if it eats. I tried the Finicky Fish formula, but I wasn't as close to the tank as I liked to see if it ate them. I'll observe again today. I tried LRS Reef Frenzy this time and while he picked at it, he spit it back out, but then continued to pick at it once again. I'm guessing he doesn't like big chunks of food. He's now picking on Julian Sprung's Sea Veggies (is that nori?).
Is it worth a shot to try clam in a half shelf? I have access to some.
