Diadema setosum – Nocturnal Browsing Diadem Urchin

Diadema setosum, better known as the diadem urchin, is a formidable nocturnal echinoderm against algae. This specimen, native to tropical reefs, is highly valued for its ability to graze unwanted algae on live rocks, decorations, and hard-to-reach areas of the reef tank.

A nocturnal cleaner with impressive spines

The diadem urchin is distinguished by its extremely long spines, which can bring its total size up to 40 cm. Naturally discreet, it hides during the day and becomes active at night, making its action effective without disturbing the tank's life during lighting hours.

Be cautious with young corals

Although it does not damage adult corals, it can sometimes disturb or displace juvenile or freshly settled corals during its movements. It is therefore advisable to secure the cuttings well and monitor during the first days of introduction.

Maintenance conditions

  • Recommended minimum volume: 300 liters
  • Temperature: 22°C to 28°C
  • pH: 7.5 to 8.5
  • Activity: primarily nocturnal
  • Behavior: peaceful, very useful against algae

Why choose Diadema setosum?

  • Effectively eliminates invasive algae
  • Ideal for well-established reef aquariums
  • Discreet and nocturnal behavior
  • Original and aesthetic presence in the tank
  • Compatible with most fish and invertebrates

Diadema setosum is a valuable ally against unwanted algae. Thanks to its spectacular spines and nocturnal efficiency, it ensures a natural regulation of the microflora while adding a wild touch to your reef decor.
