Long Spine Urchin (Diadema setosum)



We do not ship fish or Inverts at this time. These items must be picked up locally  Thank you.

The Black Longspine Urchin is useful in reef aquariums because it will eat Green Hair Algae.

Behavior: It is also useful for controlling algae in aquariums containing aggressive fish that may eat other invertebrates. They are nocturnal and spend the night grazing while the fish sleep. When they feel threatened by a fish they will actually point their spines at the fish to protect themselves.

Venom: The Black Longspine Urchin is venomous so be careful not to get poked. The sting is similar to a bee sting.

Feeding: If no algae is present in the aquarium you may supplement the Black Longspine urchin's diet with live macro algae and dried seaweed (nori).

Tip: Don't forget about your water parameters when combating algae blooms. Water chemistry is every bit as important as a good clean-up crew.
