Cidaridae, commonly known as Pencil Urchins, are a family of sea urchins characterized by their thick, blunt spines that resemble pencils. They are found in various marine environments from shallow reefs to deep-sea habitats. Pencil Urchins are known for their hardy nature and ability to adapt to different conditions, making them a suitable choice for reef aquariums. They play a beneficial role in the tank by grazing on algae, helping to keep the aquarium clean. However, their spines can be sharp and may harm more delicate tank inhabitants.
