I found this lil guy on the glass this afternoon, tis about 5mm across and just wandering around.

Any thoughts as to good/bad/etc?

They rackon theyre bad, but not sure why.

I have a few...just leave them unless they can be got real easy.

well it's easy to get, but unless I have a good reason to get it out, the gf will kill me (it's cute, you see ).

link to aforementioned badness?

They multiply to plague proportions

its a asterina sp., harmless starfish but can multply into large numbers.

Get rid of it they breed like crazy and eat coraline algae.

Consider it gone Thanks all.

Get rid of it they breed like crazy and eat coraline algae.

no proof of that, some say it eats algae. everybody i know has some in their tank and have coraline algae. some even say they corals.

again no real proof. i keep mine because i do not see them as a problem.

lol, one day they might be considered an esential part of a clean up crew.

i have got quite a few but dont really bother with removing them, cant say ive ever seen them do anything bad, the majority of them that i can see tend to head towards the back glass where the algae is (not corraline)

Have you guys seen those snake-star things? I was reading through an underwater NZ photography book, and they were from dives in the Milford Sounds. Very cool colouration black and white stripes, I had never seen a starfish like that.

Could they be kept in a refridgerated tank?
