He looks really good. I am very happy with my recent addition of a powder brown. Mine is still eating really good after being added to the main. I am sure yours is too. They are awesome looking fish. Especially when they flare their fins up with that nice orange stripe and flourescent blue outline.
The football works nice The clip is zip tied to a small piece of lr. I use a long piece of rigid airline with a plastic hook on the end to put it in the tank and pull out the empty clip. I just hook the zip tie. It works great. I don't even get my hands wet. The fish know the airline means food and they go wild as soon as I put it in to pull out the empty clip.
I have been doing that football trick to after seeing a thread about it on here. It has been working great for my two tangs. Are you suposed to put the Nori towards the bottom of the tank? I typically see it down there, but I just put the suction cup right at the surface. Does it make any difference whatsoever?
