Starfish?

[Bruen]

Does anyone know if these are starfish and if so what kind? There are about six on my coral and are blue.

Cant really see them that good but are probably asternia stars. I`ve never had any problems with them.

Asterina Stars...most varieties are fine...good detrivore's...one or two varieties have been known to much on zoas I think...I have hundreds if not thousand in my tanks... The grey and silver are the ones that munch on zoas... Look at them in a regular light... Not actinic to tell the true color
