i took the nori out, he didn't seem interested and i didn't want it disintegrating. i have some ulva in my sump, might put a tiny piece of that in for him. there is some live rock in the qt with some algae and there's algae on the back wall he's been out picking at. he's also eat a little mysis and brine shrimp. he's the shyest fish i've had so far!
