Creature ID?
 

Hi,

Does anyone have any idea what this might be? I couldn't get a very good photo of it. I must have came as a hitchhiker on my live rock. Let me know if you need any more information. Thanks.

Asterina starfish

Thanks for the quck id. I'll do some research on it now that I know what it is to determine if I should keep it.

I have a lot. Seem to eat algae only

There's a myriad of different Asterina star species all preying on different food sources. Most are regular herbivores/ detritvores but some prey on soft corals such as zoanthids.

I just remove all of them from the tank, no point taking chances.

I must be lucky, they leave my zoas alone but I do not have sps in the tank

Thanks for all the comments. Good to know. I'll keep an eye on it and see what happens.
