grass in a reef tank

[cabin]

I'd like to set up my new 180 gallon with seagrass in one section, a reef in the other. Although I've seen some threads of people who seem to have done this, I'm not sure about whether my current fish, and new fish I'm considering, will more or less leave the grass alone. I do have one dwarf angel (Coral Beauty) and one tang (Scopus). I was considering adding another tang when I introduce the fish to the new tank. I'm thinking some species of tang might be better than others when it comes to leaving grass alone. Anyone had experience with the Scopus, Powder Brown (Acanthurus japonicus) and Flame Fin Tomini Tang (Ctenochaetus tominiensis) in a reef/grass tank? The Tomini supposedly eats diatoms off of rock, which made me think it would be more prone to leave grass alone than the others. Any thoughts on this would be appreciated. If you think I'm crazy to even try this, let me know! Thanks

Socpus tang will nip off the ends of turtle grass.As far as other grasses IDK.

Hmmm. Judging from the genus name the Tomini is a bristletooth, yes? Should be fine with the grasses. The Powder and the Scopus I'd worry about, just personally from some experimentation in fish shops.

Individual tastes acknowledged, I'd probably try to rehome them if you go with adding in grasses.
