I have had one of these come in on a coral . It is a single thread which can stretch out to a few inches long and seems to have small hairs on it. It will float in the current and then pull itself in. Its base is rather small maybe an 1/8". I tried to manage them but have quickly risen in numbers. There are probably about 30 of them now that I can count in a couple of months time.
Does anyone know what it is? Can I or should I do something about it?
Thanks for your answers
