What eats calciferous algae?

[Theulli]

I am thinking about inverts for my tank that has halimeda , shaving brushes, etc. will a pincushion urchin eat those? Emerald crab? Anything in particular I do need to avoid with these algaes?

thanks!

Urchins eat coralline algae.

Cool because I just got a whole bunch of different species of these delivered and with some algaes my pincushion acts like a kid in a candy store

Fairly certain urchins will go after the macros too.

Even the hard ones like shaving brushes? I know it eats ogo and chaeto like crazy

A 2 min google search gave me examples of them eating halimeda. My urchin would likely not bypass a good meal but does tend to stay on the glass.
