In my 20 hex, I have probably 500 micro brittle stars. I understand Paul talked about these at one of the meetings recently, and he has received the first ones I've managed to remove. I have no real idea how to optimize the survival of these, as they are hitchhikers. That tank is coming up on four years old, and I just noticed them about a year ago. The best method of transplant appears to be by removing caluerpa with them on it. That red stringy "tang heaven" stuff grows in that tank, and they flock to it. It will be a while before I can remove any more, but you might want to start a list if anyone is interested. If anyone has any other suggestions on getting them out safely, please let me know.
