Without a picture, no.
The Bali star is not what you describe. So not sure there. If they are like chocolate chip stars they may be similar.
But with any star, you need to know this:
The tank should be at least 6 months old
For a "reef safe star" (and never buy one until you know) you need a very large tank, often over 100g with 150+lbs of LR.
Water parameters should be pristine (which means even for predatory stars, a decent size tank)
Specific gravity should be 1.025-1.026
Acclimation is critical for all stars, and should be a drip method
Predatory stars will comsume corals, clams, scallops, snails and many other things
Reef safe stars can not be spot fed and need the large tank mentioned above
These are some of the most delicate animals we can add. It is really important to not buy one until you can get a picture and a more specific ID. Lots of seastars - perhaps the majority IMO - will die in this hobby.
