What it is

I found today like small star fish what it is

Looks like an asterina star. Most are harmless but some varieties can eat coral. If you have coral and it doesn't look like it's being eaten, probably harmless.

Asterina. They are an invasive species but are also great tank cleaners. I personally would remove all specimens unless you want an outbreak. If you see 1, you most likely have more in the tank.

Could b a lot of things... Sponge. Vermitide snail. A worm curled up....I would take it out dip the coral and scrape off what I could....just to be safe.
