It is nice looking! I have better luck growing gorgonians in my seahorse tank than the macro algae. I am jealous. I don’t believe you will have any issues with it taking off like some of the algae we deal with. Some fish may eat it, but it adds a nice contrast to the rock and corals.
I hope so. I am colorblind but this thing actually looks nice to me. Kinda weird. I see the oranges a little better than others. Some seems so drab. But this thing I can see well! Constantly asking the wife what color the corals are.
