Is this a baby starfish?

Asterina starfish. Some are good, some are bad.

And it's not a baby, it's full grown, albeit small.

The rule on good versus bad that was explained to me is that if they are light in color (whitish), they are reef safe. If they are a dark colored, they might be a problem.

This has been my personal experience.

My last tank was full of the white ones. I really like that they kept the coraline in check. Never damaged a coral.

Thanks. Only see it when I turn the lights on in the morning and then it slowly crawls back to its little cave. Doesn’t seem to be attracted to any of my (very few) corals atm. I’ll keep an eye on him.

If you see one, you have 100 They drop legs and reproduce pretty quickly if the conditions are right. I remove 10-15 every time I do a water change.

Asterina starfish. I’ve never had them, but some will eat coral and some won’t. Just depends

I used to think they were great, until I started seeing my zoas disappear. Definitely keep an eye on them.

The tank I had 5 years ago had a ton, because I thought they were very interesting and love the 'live' element they brought to the rock and sand. My recent tank I have zero and want to keep it that way. They reproduce at an exponential rate, as well as eat coraline algae. IMO once they decrease the amount of coraline they start looking at other food sources. I have never had an issue of them eating corals, but enough people have for me to be alarmed. Also I am not a fan of anything that can reproduce so easily. Once you have them there is no way to get rid of them without killing all of your other inverts.

They can actually be removed pretty easy with some Harlequin Shrimp but once their food supply runs out they need to be fed starfish or removed from the tank.

Asterina starfish in my opinion there both bad some eat coraline and coraline helps coral so put it in the sump.
