Biscuit Starfish, Tosia queenslandensis, is a glowing bright red/orange starfish with distinctive polygonal shapes across its back.  Biscuit Starfish will scavenge the floor for meaty foods including sponges, sea squirts, and some algae. This species of starfish is especially susceptible to changes in water quality and will adversely react if this is done.  The Biscuit Starfish will also be a beneficial member of your tank keeping it clean by feeding on algae.
