Resolved ID this please. (some sort of starfish maybe?)

It's an asterina star. You might want to keep an eye on it.

 

It could be a "Asterinid sp" but I'll let they pro tell you about that when she arrives

 

It might be an asterina star but it doesn't really look like the ones i've seen before

 

Ditto

 

i found this on the garf site about these bad little stars

The starfish is Asterina anomala and is common on many reefs in the Indo-Pacific.
This fissiparous* starfish is carnivorous on sessile animals including corals.
It usually occurs under rocks on reef flats. The mottled coloration makes the starfish very cryptic:

 

Maybe an Asterina Phylactica?

 

Gresh's cavalry is here. It appears to be an asterinid star which means it belongs to the family Asterinidae. They are extremely difficult to id even to genus, let alone to species, and especially if it's a small one. This looks as if it's regenerating although I can't tell if that's because it split in half or if something ate some of it. Different species have different food preferences. You can't predict what one will eat just by looking at it.....unless of course it has its arms wrapped around a coral & its stomach out! The majority of the ones that show up in tanks are harmless micro-grazers.

 

well then, I guess he shall stay out of the tank lol

thank you everybody!

 

that is a brittle star fish, i have one or two of them. goood part of the clean up crew..nice hitch hiker.

 

It's an asternia that has dropped legs. That is how they reproduce.
