Starfish, maybe Asterina, that’s usually what we get.
Some like them, I remove, your choice.
They can multiply real fast.
 
Thank you for the super fast response.
Rather not fight on two fronts at the same time…. battling with a small bubble algae infestation already.
Kind of like the look of this starfish
Do they get bigger?
 
Asterina star, mostly harmless and will consume algae (coralline mostly) and reproduce rapidly. There are a few that eat coral, but that’s usually not the case. Most people remove them, but I don’t consider them to be a pest (some do).
 
For bubble algae, manual removal if you can, then emerald crabs (females) and maybe foxface (50/50) for larger tanks. Keeping nutrients under control is the underlying issue with valonia.
