Just Curious:

How much nutritional value is there in green hair algae? If a tank had a
generous amount, could a small Yellow or Hippo Tang live off it for a week
without added food?

Sure. Even if it didn't eat much of it, it would probably do fine. (My
tangs don't touch green hair.) I've been told a happy, healthy and well
fed fish should do fine for 5 days without food anyway. (Not that you
should starve your fish if you can help it. This was brought up as a
technique for getting picky eaters to try something it finds less
appetizing.)

Speaking of tangs. It's been brought up that giving tangs nori and
wakame acquired from natural/health food stores is a good deal and great
for the fish so I'd thought I'd throw it out there to try Dulce (it is
red, soft and a little sticky when dried - maybe folks on the Eastern
seaboard of the US can get it fresh and grow it in your refugiums.) It
is tang crack.
