Just a quick update. I rubberbanded the nori to a rock and he started eating. I then started putting it on the clip and he ate it there. Then I put some frozen food that my local pet store makes in there and he ate it. Just yesterday I put him in the 75 gallon tank where he is doing fine. He's in there with a chalk bass, royal gramma, spotted cardinal, and diamond goby. Peace hasn't been established yet, but hopefully will soon.
