I suppose most people finally join the forums when they have a question that they cant seem to answer. I've been reading this site for quite a while and I like what I've seen.... so here's the question that brought me in:

How do serpent stars reproduce?

I'm asking because I've had my 75 gallon tank for 3+ years and luckily haven't had any "major" crashes. I never had any serpent stars in the tank as I was under the impression that the sand sifting stars were sufficient. I watch the tank at all hours, even at night and have never seen any that may have hitchhiked. After a "sort of crash" I put one bristle star and one serpent star in to clean up the detrius a bit better at the live rock edge and in all the places that are hard to get to.

I now have one brittle star and three serpent stars. And the kicker is, as much as I think I stare at the tank, I never saw the new ones until they were pretty good sized. (about half the size of the one I purchased)

Not that I'm complaining, I like them, but how did I get them? Do they reproduce asexually? If you can point me to something, that would be great. I'm apparently not Googling it correctly. :)
 
Hi Toga!

I am thinking of making my next tank SW, so I am in a kind of research mode with all this stuff...

Anyway, I thought your question was interesting so I looked and found this link:

If this is the correct type of brittle star, they can reproduce asexually. At least maybe this link will get you started...

Welcome to AA!
 
Thanks Tigerlily!

Now I think the question is, is there such a thing as too many brittle stars? And if so, will they stop reproducing before that point?
