Tuxedo pincushion urchins display a striking pattern of alternating dark blue/black and red/orange bands that resemble a tuxedo jacket. Smaller than red pencil urchins and less destructive to aquascaping. Excellent algae control and one of the better invert choices for nano reef setups.
Native range: Indo-Pacific. Most US trade specimens come through marine wholesale suppliers in Indonesia, the Philippines, Hawaii, and the Caribbean. Wild collection remains the primary sourcing method for the majority of marine inverts - few are captive-bred at commercial scale. Quality of acclimation at the wholesale/retail stage is the biggest single predictor of long-term survival in home aquaria.
Tank size: 30 gallons. Parameters: temperature 74-82°F, salinity 1.024-1.026, plus the standard reef tank requirements - stable calcium 420-440 ppm, alkalinity 8-10 dKH, magnesium 1300-1400 ppm, nitrate under 25 ppm, phosphate under 0.05 ppm. The species requires conditions consistent with a healthy reef tank rather than nutrient-stripped sterile water - well-established systems with diverse microfauna and biofilm typically support these inverts better than newly-cycled tanks.
Lighting: depends on species. Photosynthetic inverts (clams, anemone-symbiotic species) require high-PAR reef LED lighting. Filter-feeders (worms, scallops) prefer moderate lighting and benefit from particulate-rich water. Flow: moderate, indirect flow works for most inverts - direct high-velocity flow stresses or damages soft-bodied species.
Acclimation: drip acclimate over 2-4 hours for hardy species, 4-8 hours for sensitive species (Linckia stars, sea hares, demanding nudibranchs). Never expose inverts to air during transfer - capture in a bowl underwater and transfer wet.
Tuxedo Pincushion Urchin diet: Algae, biofilm, occasional detritus. Feeding strategy depends on dietary type. Algae eaters require established tanks with biofilm and microalgae growth - new tanks lack the algal base they need. Carnivore inverts (starfish, some snails) need targeted meaty feedings 2-3x weekly. Filter feeders (clams, worms, scallops) need phytoplankton in the water column. Photosynthetic species need adequate lighting plus supplemental amino acid or coral food dosing.
Safe: Most reef-safe community.
Avoid: Fish that eat small inverts.
Not captive bred.
Coralline depletion in small tanks; "decoration carrying" can attach to small corals.

The Tuxedo Pincushion Urchin is rated beginner to intermediate difficulty on this care sheet. It needs a tank of at least 30 gallons, a temperature of 74-82°F and salinity of 1.024-1.026. Adults reach about 2-3 inches and live 3-5 years. Tuxedo pincushion urchins display a striking pattern of alternating dark blue/black and red/orange bands that resemble a tuxedo jacket.

Coralline depletion in small tanks; "decoration carrying" can attach to small corals. Keeper note: Less likely to knock over rockwork than larger urchin species. Will pick up shells, frag plugs, and small debris on the spines (camouflage behavior). Flow: moderate, indirect flow works for most inverts - direct high-velocity flow stresses or damages soft-bodied species.
