About this item

Blue Eyes Fire Urchin

The Blue Eyes Fire Urchin (Astropyga radiata), also known in the hobby as the Fire Urchin, Blue Spot Urchin, and Blue-Spotted Sea Urchin, is one of the most visually spectacular invertebrates you can add to a saltwater system. Its deep crimson red body is adorned with clusters of iridescent electric blue spots arranged in radiating bands between its long, dramatic spines — glowing like a constellation of blue eyes staring back at you from across the tank. Under reef lighting, the contrast between the fire-red body and the vivid blue clusters is nothing short of breathtaking.

Beyond its extraordinary appearance, the Blue Eyes Fire Urchin is a tireless and effective member of the cleanup crew. It forages constantly — grazing algae from rockwork, glass, and substrate around the clock as it moves through the tank. As a true omnivore it will also consume detritus, decaying matter, and uneaten food, making it one of the most hardworking and complete natural janitors available in the saltwater hobby.

This is the rare combination of a functional cleanup animal and a genuine display showpiece — the kind of animal that draws comments from every person who sees your tank for the first time.

Special Considerations

Handle with care — the spines of this urchin are mildly venomous and can cause a painful sting if touched directly. Always use gloves or a container when handling. Like all urchins, the Blue Eyes Fire Urchin moves continuously as it grazes and can dislodge unglued rockwork, frags, and corals in its path — ensure your aquascape is stable and secure. Supplement its diet with dried seaweed sheets if algae levels are low to prevent it from grazing on coralline algae. Sensitive to sudden changes in salinity — always drip acclimate on arrival.

🔍 Aquarium Insights

The Blue Eyes Fire Urchin is a standout addition to any reef or FOWLR system:

  • One of the most visually dramatic invertebrates in the saltwater hobby — no other urchin comes close for pure visual impact
  • A complete cleanup crew member — grazes algae, consumes detritus, and scavenges uneaten food simultaneously
  • The rare animal that earns its place both as a functional janitor and as a genuine display centerpiece
