I guess I dont know my algaes yet. My tang is constantly eating off the rock
in my tank. It definitely looks like it`s ripping algae off the rock. I
would imagine there are probably plenty of green algaes that are not
technically "Hair" algae, right?

Over time the tang will eat off the rocks all algae which
tastes good and leaves the algae which does not taste good.
And this one will outcompete the other kinds... if your
water conditions are not good and hair algae likes to grow.
