Leafy macro id

[mjschomer]

Can anyone identify this greenish leafy algae? It's growing all over one of my Kaelini rocks and seems to be spreading quickly.

Also, whatever it is... Does anyone know of anything that will eat this stuff?

Hi mjschomer,

Do you think it could be a species of Dictyota? I have heard that Diadema urchins will eat it but these guys may also eat sps corals and other desireable things.

HTH,
Kevin
