Hitchhiker star fish
 

Just notice of late that my 12 gal is breaking out with these start fish.
For a 12 gal, i'm guessing that there's at least 20-30 of these little guys.
Should i do something about this or just let them be?

thanks,

Perfectly safe they will not get any bigger unless they are green brittle stars they can get pretty big

They're probably Asterina stars. Have a look here for more info:

I have 2 types of hitchhiker stars. One is the type that Christy mentioned. The 2nd type is the Ophiuroids. I like those. Those are cool. They came along with my blue sponges.

Some of in Calgary put those in our tanks on purpose, as they are excellent scavengers. At feeding time my tanks are a sea of arms, and I love it. :eek:

I have 100 of those lil guys in my tank :eek:
