Appearance
This species has a dark brown body with a blunt head and elongated shape. Its short precaudal tail and lighter underside distinguish it from larger nurse shark relatives. Small spiracles behind the eyes allow it to breathe while resting on the substrate, a hallmark of bottom-dwelling nocturnal sharks.
Care & Requirements
The ORA Short-Tailed Nurse Shark thrives in large marine aquariums with fine sand substrate and excellent filtration. Maintain pristine water quality with ammonia and nitrite at zero, and nitrates below 20 ppm. Use a high-capacity protein skimmer to handle the species’ bioload. Provide moderate lighting, smooth décor, and open swimming areas. Feed a rotation of fresh shrimp, squid, and marine fish 2–3 times per week. These sharks rest motionless during the day and become active at night.
Is the Short-Tailed Nurse Shark reef safe?
No. It will consume small reef fish and invertebrates, so a fish-only system is best.
Can this shark be kept in pairs?
Only in systems exceeding 400 gallons, introduced as juveniles.
What signs of stress should I watch for?
Rapid gill movement or pacing along the glass indicates oxygen deficiency or poor water quality.
Tank Mates & Compatibility
Compatible with large, peaceful marine fish such as tangs, angels, and groupers that don’t occupy bottom space. Avoid aggressive species or other bottom-dwellers that could provoke conflict. Only house with other sharks in very large custom systems exceeding 400 gallons.
What fish can live with the ORA Short-Tailed Nurse Shark?
Large, calm species that ignore its resting areas.
Can I use invertebrates as a clean-up crew?
Not recommended—most will be eaten.
Do they show territorial behavior?
Minimal, though they may guard favorite resting zones.
Aquaculture / Availability
ORA is one of the few breeders successfully producing captive-bred Short-Tailed Nurse Sharks. Eggs require over five months to hatch, and juveniles readily accept prepared seafood diets. Captive-bred individuals are hardier and adapt quickly to aquarium environments. Due to slow breeding rates, ORA releases this species seasonally in limited quantities.
Are ORA Short-Tailed Nurse Sharks always captive-bred?
Yes—wild collection is extremely rare.
When are they available?
Usually in small seasonal batches throughout the year.
Why choose a captive-bred shark?
Captive-bred sharks adapt faster, carry fewer parasites, and support sustainable aquaculture.
