Spineless Sea Urchin Red and Blue Mespilia Globulus

Overview:
The Spineless Sea Urchin (also called the Blue Tuxedo Urchin) is a small, reef-friendly echinoderm prized for its brilliant blue and red bands and short, blunt spines. Unlike many urchins, its spines are rounded and non-piercing, making it a much safer choice for community reef tanks.

Origin:
Native to Indo-Pacific reefs, especially around Fiji, Tonga, and Indonesia, where it inhabits coral rubble zones and lagoons.

Feeding:

• Primarily an algae grazer, consuming coralline and film algae.
• Will also scavenge detritus and leftover food.
• Can be supplemented with nori, spirulina, and algae wafers.

Tank Mates:

• Completely reef-safe and compatible with corals, clams, and most peaceful fish.
• Avoid housing with predators that eat echinoderms (e.g., triggers, puffers, large wrasses).

Aggression Level:
Peaceful. Non-aggressive and harmless to other tank mates.

Experience Level:
Beginner-Friendly. Hardy and easy to keep, provided the tank has enough algae growth or supplemental feeding.

Water Parameters:

• Temperature: 74–80°F (23–27°C)
• pH: 8.1–8.4
• Salinity: 1.023–1.025
• Tank Size: 30+ gallons

Unique Features:

• Brilliant blue and red banding with short, non-stinging spines.
• Will often carry shells, coral rubble, or algae on its back as camouflage.
• Excellent at natural algae control in reef tanks.
