Appearance
The ORA Variegated Sea Urchin has a rounded pincushion shape covered in short, variable-colored spines ranging from greenish to tan. Its unique camouflage behavior often leads it to carry shells, algae, or small rubble across its body, blending into the aquascape while feeding.
Care & Requirements
This urchin thrives in stable, mature aquariums with plenty of live rock and a natural growth of algae to graze on. A 30-gallon tank is the minimum recommendation, though larger systems offer more stability. They feed primarily on algae and biofilm but should be supplemented with dried seaweed sheets or algae wafers if the tank lacks natural growth. Maintaining stable parameters is crucial—temperature between 75–78°F, salinity 1.023–1.026, pH 7.7–8.5, and nitrates under 20 ppm. Good water quality and routine maintenance ensure longevity and health.
- Do ORA Variegated Urchins need supplemental feeding?
Yes, if algae is limited, offer dried seaweed or algae wafers. - Can they damage corals?
They are generally reef safe but may knock over loose frags or scrape delicate tissue when climbing.
Tank Mates & Compatibility
The ORA Variegated Sea Urchin is peaceful and coexists well with most reef-safe fish, shrimp, snails, and corals. Avoid predatory tank mates such as triggerfish or large wrasses that may nip at urchins. Multiple urchins can be kept together in larger tanks, though their heavy grazing means adequate algae or supplemental feeding is required.
- Are they compatible with clownfish and shrimp?
Yes, they coexist peacefully with most community reef species. - Can multiple urchins live together?
Yes, provided the tank is large enough to support their algae needs.
Aquaculture/Availability
ORA has successfully captive-bred the Variegated Sea Urchin, making it one of the few aquacultured echinoderms available to hobbyists. This reduces pressure on wild populations while ensuring hardier, more adaptable specimens. Currently, captive-bred specimens are available seasonally and may sell out quickly due to high demand.
- Are ORA Variegated Urchins always captive-bred?
Yes, ORA exclusively produces aquacultured specimens. - Is availability year-round?
Stock is limited and may not always be available; pre-ordering is recommended when possible.

FAQ
How long do ORA Variegated Sea Urchins live in aquariums?
They typically live 3–5 years in captivity with proper care, stable water parameters, and adequate feeding. Some hobbyists report longer lifespans in larger, well-maintained systems.
What do Variegated Sea Urchins eat in home aquariums?
They graze on hair algae, coralline algae, and biofilm. If natural algae is insufficient, supplement with dried seaweed sheets, algae wafers, or fresh macroalgae.
Are Variegated Sea Urchins safe for reef tanks?
Yes, they are considered reef safe, though they may knock over loose coral frags while grazing. They do not deliberately eat healthy corals.
What tank size is best for ORA Variegated Urchins?
A 30-gallon tank is the minimum, but larger systems provide better long-term stability and enough algae growth to sustain them.
Do they require special lighting or flow?
No special requirements beyond standard reef conditions. Moderate lighting promotes algae growth, while normal flow patterns are sufficient.
Can they be kept with other algae grazers?
Yes, they can coexist with tangs, snails, and hermit crabs, but heavy competition for algae means supplemental feeding may be required.
Do ORA Variegated Urchins reproduce in captivity?
While possible, successful spawning events are rare in home aquariums and usually occur only in specialized breeding systems.
How do they protect themselves?
They rely on their spines and camouflage behavior, often carrying shells or algae on their backs for extra protection and blending.
