Will Sailfin Blenny Eat Red Macro-Algae?

[The Curious]

I have an almost 5" lawnmower blenny in a 55 gallon. The whole system was just upgraded out of a 30 gallon about a week ago...thus completely disturbing the substrate of a 6 month old system. I'm testing every other day at 5ppm No3, but had been getting occasional Phosphate spikes prior to upgrading, which I have lowered to 0 through combination of water changes and Phosbuster, along with changing certain husbandry techniques. I'm planning on getting some chaetomorpha for my HOB refugium and I would like to also get a red macro algae for the main tank. I would like to do some more fragging, but would perfer to have my NO3 at 0 before cutting.

I have peppermint shrimp, turbo/Astrea snails, red+blue legged hermits, a green brittle star, who is now gone, left many small offspring in my tank, falco hawkfish, lawnmower blenny, 2 b+w ocellaris clowns, and various soft corals. Would I be able to put a red macroalgae in the main tank without it being turned into a lunch?

Thanks :beer:

My golden sailfin blenny didn't touch mine -- though I didn't have it for more then a week before my urchin ate it all.
