If this even is a starfish I used to have the little guys in my old tank but this one seems so much bigger then them ???

Asterina starfish?
The white thing on the Rocks,?

Some say they eat corals .
Some say only eat dying corals .Some say won't eat corals .
Idk as never had any ^_^

They can self propagate by dropping a leg and can get lots of them in a shirt time apparently .
Harlequin shrimp will eat them but when all asterinas gone need re- home the shrimp as only eats starfish unless buy starfish to feed him

It's an astrea. There are dozens of kinds, most are beneficial. Until you see one munching on live coral i wouldn't worry.

Id say perhaps cyano. Coralline bulges out more
