Kole tang vs Yellow tang - feeding habits

[jostafew]

Hey everyone, i'm trying to decide which of the two would be best suited to my tank; i know that they both feed on filamentous algae, but the Kole tang will apparently eat a wider variety of algae like substances. My tank seems to grow everything except for nice long green algae, more like a shorter patchy matt of algea, diatoms, a little cyano, possibly dinoflagellates again (grrrr). Is the Yellow tang gonna touch any of that stuff or is it gonna stick to only the nice green stringy type algae?

Thanks in advance
