Seen a few of these in tank today...I think count is up to 5.
I think it's a starfish but no clue. Is it coral safe?
Thanks in advance for your help.

Asterina Starfish. Most are coral safe but you should watch them for a while to see if they attack any corals. They probably won't but there are species that can eat coral.

I've noticed 3 or 4 on a brain coral...but brain was already on rock that kid got off craigslist. Lfs didn't know if brain was gonna make it. Still has some pink in it. One has a burrow like spot between brain and live rock. Will these guys get any bigger? If so how much bigger? I'd say their probably a 1/4 in big.

They will not get any bigger.
