Hi Johnny,

That is an asterina star. Here is some light reading for you:

FAQs about Asterina (tiny, white...) Sea Stars 1

yeah. they typically dont cause trouble, but multiply rapidly. i always tried to keep them out of my tank. worked for about 8 months, then there were many. after that its a loosing battle. took weimers advice on another thread. he said remove 10 a day and it will stay under control.... just too lazy to keep up on them .

a harlequin shrimp will kill em off quickly, along with any other stars, but then it would just die of sarvation and i have no idea how hard they are to catch and return either. so not a very resposible option.

...mine have never been a problem, but it's true that you'll never get them all. I have a 20L and I thought there was nowhere for them to hide for long. Even when I think I remove them all, I always find more later.

they can become problems, some of them enjoy eating zoanthid polyps. so just watch them
