I noticed a couple of weeks ago these tiny littel starfish no bigger than the head of pencil eraser tip on the walls of my tank. I now have a Brittle Star fish. Quite a while ago I have a Choc. Chip Star that got too big so I sold it. Then I had a Sandshifter or Sandsifter Star. I gave it back to the person that gave it to me. One of the baby stars has grown a little. I can barely see the design on its back. It looks like a Choc. Chip star. There are MANY of these little stars on my tank walls and have seen them on my live rock. Don't know how Choc Chip stars multiply, how to tell between a male and female. Liveaquaria I believe is a little vague on how they multiply. I will try to send a good pic of these guys.
