Hey everyone, saw a few of these guys in my tank. Not sure what they are. http://uploads.tapatalk-cdn.com/2016...1d9a39b88f.jpghttp://uploads.tapatalk-cdn.com/2016...85e08fb331.jpghttp://uploads.tapatalk-cdn.com/2016...087202746b.jpg

Asterina Starfish, usually they are harmless but they can reproduce fast. I would take them out.

Yep asterna stars, I'd dump them in the trash... If they find a food source they replicate like rabbits...

They ate all my zoas. Go down to your tank 2 hours after the lights go out and bring a flashlight.... See how many you got. Start pulling them out....

Or get a harlequin if you've got a bunch of them.......
