Brittle Star - Tiger Striped Serpent Star Profile
If you’re looking for a decent scavenger for your saltwater aquarium you may want to check out the brittle stars. They ship poorly but once they’ve acclimated to your saltwater tank they should do fine provided that your water quality is kept in the optimal range, i.e. very low nitrates, stable salinity and pH, etc.
There is now a profile on one species of Brittle Star, the Tiger Striped Serpent Star (Ophiolepis superba). Check out the full profile here: Brittle Star.
