Unsure if this really is dino or some other algae

I dont see this as dino but some dying hair algae becoming overrun with another nuisance algae known as chrysophytes. Unfortunately with this stuff, best removal is to take rock out and place in container of tank water and scrub it off with a firm toothbrush or automotive detail brush. Addition of 3% peroxide will help with cleanup.
Return rock to tank after cleaning and add some cleaners such as:
Pitho crabs
Emerald crab Females
Astrea snails
chaiton snails
Ninja star snails

Ive noticed the algae disappearing on its own or that the 4 monetaria annulus that i have are eating them, cause im noticing they start to get fewer. also i have a emerald crab already but dang knows if its a female or male didnt know it made a difference. And the only snails at my job that i work at only has astrea snails atm no ninja star snails or chaiton? do you possibly mean chiton snail? If so then i could just grab a few small ones that are at the store i work at cause they are just hitchhiking chitons that appear in the coral/invert aquarium.
