starfish, what kind?

[sil3ncio]

GOOD OR BAD FOR REEF?

Its really small now, about the size of a penny, maybe a bit smaller...

Asterina starfish. I have read that they are beneficial, but also that they spread very quickly and can annoy some corals. I occasionally see them in my tank and haven't noticed them bothering anything.

i just added rock in my tank and i have about 7 of them, thnx b/c i was wondering what kind of starfish they were

As long as they are a white/beige-ish color they are fine in your tank.
They will multiply faster if you overfeed.

The ones that are bad are smaller and have either a blue or green cast to them.

thanks for the responses!

I have what look to be the same ones in my tank but a little smaller.
Is the blue/green cast very easy to tell if they are the "bad" ones?

 

[KathyC]

It's the little ones pictured here that you need to be concerned with

 

[tonep]

Thanks Mine look like the white ones.

[KathyC]

[sil3ncio]
