yellow Tang eats cyanobacteria?

[arkman]

I have ayellow Tang that seems to be aggressivly picking cyano off my tank glass. I was concerend he was only doing it b/c he was very hungry, but I tried to give him his usual seaweed - he ate, but not super agressivly and went back to picking the glass.
Thought this was cool, anyone ever know a yellow to eat cyano?

I am still somewhat new- what is cyano?

cyano is the dreaded red "slime"....
also, many other macro and micro algea are in the cyanobacteria family...genus...phylum...whatever lol
PS...in the theory of evolution cyanobacteria is thought to be the main ingredient in "primeordeal soup"...
