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?

The problem is that green hair algae does not taste good,
so these fish do not eat it...
There would be no problems with GHA in reef tanks if
any tang would eat it :-)
