spider or brittle star?

Sounds like an alien creature.. But could be a Brittle or Serpent star great addition for a clean up crew.

Have a google those 2 and compare

If the tank contains zoanthids they could very well be zoa spiders.

Google search picnogonads (sp?).

I thought ur not supposed to put large dry rock into a running system? Wouldn't the die off cause a new tank syndrome?

one rock at week not change your water chemistry. just check water ammonia and nitrine. only should be fine .
