Algae identification

Do you guys know what is this brown algae?
It quite difficult to remove from the rock surface, its tightly anchored. Grows slow but regrows after removal…i have it in 2-3 spots
Thanks!!

Looks like Dictyota. It’s a nicer looking brown algae but can become invasive. Some have had success using Fluconazole to eliminate it. Others use manual removal. According to Reef Cleaners Pitho Crabs will eat it.

I wonder if it might be lobophora? If it is I am jealous as I bought and tried to grow it once but was not successful.

I think it looks more like Dictyota than lobophora….but its now too short to tell. If it grows longer I will take another picture before removing it. Thanks a lot for the suggestion!!!!
