Macro Algae Eater for a 40 Gallon Reef

[Jgill70]

My live rock came with some macroalgae on it, and I was wondering what I could add to my tank to help control it. I know that snails and other inverts will eat microalgae, but not macroalgae, and my tank isn’t big enough for a tang. Are there any fish or invertebrates that will eat macroalgae and are suitable for a smaller tank?

If it's macro and don't want it you can just remove. Snails often won't eat it depending on the type,after my tangs died I threw all mine in the display nofthing ate it.

What kind is it? Can help alot
