This detailed guide will help you understand everything you need to know to successfully keep and care for this exotic shark.

What Makes our Short Tail Nurse Shark For Sale Unique? An In-Depth Overview
The short tail nurse shark is a relatively small species of nurse shark native to the tropical western Indian Ocean, including coastal waters around East Africa and Madagascar. Unlike its larger relatives, this species typically reaches only about 2.5 feet (75 cm) in length, making it one of the more manageable nurse sharks for advanced hobbyists with large marine tanks.
-
Physical Characteristics: The short tail nurse shark has a broad, flattened head with small eyes and a short, thick tail that distinguishes it from other nurse sharks. Its skin is smooth and usually brownish-gray, sometimes with subtle mottling or spots that provide natural camouflage on sandy or rocky ocean floors.
-
Behavioral Traits: This shark is nocturnal and benthic, meaning it spends most of its time resting on or near the substrate during the day and becomes more active at night when it hunts. It is generally peaceful and non-aggressive, making it compatible with other large, calm marine species in a well-maintained aquarium.
-
Breeding and Lifespan: The short tail nurse shark (Pseudoginglymostoma brevicaudatum) is an oviparous species, meaning it lays eggs with an incubation period of about 165 days. While captive breeding is rare, successful hatching has been documented, highlighting its reproductive potential in controlled environments. These sharks do not provide parental care after laying eggs. Known for their impressive longevity, short tail nurse sharks can live 30 years or more in captivity, making them a long-term commitment for aquarists. Their critical conservation status makes captive breeding efforts especially important for preserving the species.

Detailed Care Requirements for Your Short Tail Nurse Shark
Keeping a short tail nurse shark requires dedication, a well-planned aquarium setup, and attention to water quality and diet. Here’s a detailed breakdown of the care essentials:
Best practices for acclimatizing a Short Tail Nurse Shark to a new environment
Proper acclimation is essential to minimize stress and ensure a smooth transition for your new short tail nurse shark into its aquarium. Sharks are sensitive to sudden changes in temperature, salinity, and water chemistry, so a gradual process is necessary:
-
Temperature Equalization: Upon arrival, keep your shark sealed in the shipping bag and float the bag gently on the aquarium surface for 20–30 minutes. This allows the water inside to slowly match the temperature of your tank, preventing thermal shock.
-
Transfer to Acclimation Container: Carefully move the shark and shipping water into a clean, aerated container or quarantine tank. Avoid adding the shipping water directly into your main aquarium to reduce the risk of introducing contaminants.
-
Drip Acclimation: Set up a slow drip using airline tubing to add tank water into the container at about 2–4 drops per second. This gradual mixing over 1–2 hours allows the shark to adjust to differences in salinity and pH gently.
-
Lighting and Environment: Dim your aquarium lights during the introduction period to reduce stress. Provide a calm environment with minimal disturbances to help the shark settle.
-
Final Transfer: Using a soft net, carefully transfer your shark to the aquarium after acclimation. Avoid pouring the acclimation water into the tank, and monitor closely for any signs of distress such as rapid gill movement or erratic swimming.
Diet & Feeding Guide
The short tail nurse shark is a carnivorous benthic feeder that requires a variety of fresh or frozen meaty foods to thrive:
-
Natural Diet: In the wild, they primarily consume crustaceans, mollusks, and small fish found on the ocean floor.
-
Captive Diet: Feed your shark a varied menu including fresh or frozen shrimp, squid, crab meat, clams, and small fish like silversides or herring.
-
Feeding Frequency: Offer food 2 to 3 times per week, placing it directly on the substrate to encourage natural foraging habits.
-
Feeding Technique: Use feeding tongs or sticks when necessary to deliver food directly to the shark, especially if housed with competitive tankmates. Promptly remove uneaten food to maintain optimal water quality.
-
Behavioral Note: Short tail nurse sharks are mostly nocturnal feeders, so feeding during dim lighting or early evening hours can encourage natural feeding behavior.
Tank Setup & Habitat: Creating an Ideal Environment
To maintain optimal health and well-being, replicating the shark’s natural habitat within your aquarium is key:
-
Tank Size: A minimum of 1,000 gallons is recommended for juvenile sharks, while adults do better in tanks or indoor ponds upwards of 1,500 gallons. The tank should be at least four times the shark’s length and twice its width to provide ample swimming and resting space.
-
Substrate: Use a soft, fine sandy substrate to protect the shark’s sensitive belly and allow it to forage comfortably. Avoid coarse gravel or sharp materials that might cause injury.
-
Decorations: Incorporate plenty of caves, rock formations, and crevices that serve as hiding and resting spots. Exposing shaded areas helps reduce stress and mimics the shark’s natural benthic environment.
-
Water Conditions: Maintain tropical marine conditions with temperatures between 75–80°F (24–27°C), salinity of 1.020–1.025 SG, pH 8.0–8.4, and high dissolved oxygen levels.
-
Filtration & Circulation: High-quality biological, mechanical, and chemical filtration is essential due to the shark’s carnivorous diet, which produces substantial bio-load. Provide strong water flow and aeration to ensure oxygen-rich water throughout the tank.
-
Lighting: Moderate to low lighting replicates the shark’s natural nocturnal and crepuscular activity patterns. Include shaded or cave areas where the shark can retreat from bright light.
Recommended Water Parameters for Short Tail Nurse Shark
Maintaining pristine, stable water conditions is crucial for the health and well-being of your short tail nurse shark. Aim to replicate its natural tropical marine environment as closely as possible:
| Parameter | Ideal Range | Notes |
|---|---|---|
| Temperature | 75–80°F (24–27°C) | Tropical environment favored |
| Salinity | 1.020–1.025 Specific Gravity (SG) | Standard marine salinity |
| pH | 8.1–8.4 | Slightly alkaline, stable environment |
| dKH (Carbonate Hardness) | 8–12 dKH | Helps buffer pH |
| Ammonia | 0 ppm | Toxic even in trace amounts |
| Nitrite | 0 ppm | Toxic to sharks |
| Nitrate | < 20 ppm | Keep as low as possible through water changes |
| Dissolved Oxygen | High | Strong aeration and circulation needed |
Filtration & Water Quality
Short tail nurse sharks are messy eaters and produce a considerable bio-load, making high-quality filtration and regular maintenance essential:
-
Filtration System: Use a robust combination of mechanical, biological, and chemical filtration to maintain crystal-clear, pristine water. Mechanical filters remove solid waste and debris; biological filters support beneficial bacteria to break down ammonia and nitrite; chemical filtration (such as activated carbon) removes dissolved organics.
-
Protein Skimmer: Highly recommended to remove dissolved organic compounds from the water, improving water quality and oxygen levels.
-
Regular Water Changes: Perform partial water changes of 10–20% weekly or biweekly to keep nitrate levels low and maintain chemical balance.
-
Water Monitoring: Test water parameters frequently, especially after feeding or stocking new animals, to ensure ammonia and nitrite remain at zero and nitrate stays below 20 ppm.
-
Water Movement: Provide moderate to strong water circulation to ensure good oxygenation, but avoid harsh currents that may stress the bottom-dwelling shark.
Lighting Requirements
The short tail nurse shark is naturally nocturnal and crepuscular, preferring low-light or dim environments:
-
Lighting Intensity: Use moderate to low lighting levels in the aquarium to mimic dusk and dawn conditions.
-
Shaded Areas: Include caves, overhangs, or rock structures that offer shaded retreats where the shark can rest during daylight.
-
Photoperiod: Maintain a natural day-night light cycle of about 10-12 hours of light, using timers for consistency.
-
Avoid Sudden Lighting Changes: Gradually adjust lighting during acclimation and avoid abrupt switches that may startle or stress the shark.
Combining these water parameters, filtration strategies, and lighting conditions will create a healthy, naturalistic environment for your short tail nurse shark to thrive. Providing pristine water quality and proper habitat greatly reduces stress and supports strong immune function, ensuring your shark’s longevity and vibrant behavior.
Tankmates & Compatibility of the Short Tail Nurse Shark
The short tail nurse shark (Pseudoginglymostoma brevicaudatum) is generally peaceful and low-activity, making it suitable for aquariums with carefully chosen tankmates. The ideal companions for this shark are docile, mid-water saltwater fish that won’t harass or nip. Recommended tankmates include:
-
Tangs (e.g., surgeonfish species)
-
Damsels (non-aggressive varieties)
-
Anthias
-
Other peaceful reef fish that occupy different swimming zones and are not overly territorial or aggressive
This species prefers to rest on sandy bottoms and remain mostly inactive during the day, becoming active primarily in the evening. Providing a calm, low-stress environment is essential to avoid unnecessary conflicts or competition.
Species to Avoid in the Same Aquarium
Certain fish and marine species should be avoided as tankmates due to their aggressive behavior or their potential to be preyed upon by the shark:
-
Aggressive or nippy fish such as triggers, puffers, and large angelfish, which may harass or stress the nurse shark
-
Small fish and invertebrates including many damsels, gobies, shrimp, or crabs that could be seen as prey
-
Highly territorial species that may intimidate or injure the shark
-
Other large predatory fish or fast-moving species that could compete aggressively for food or space
Avoid mixing this shark with delicate reef species or coral as it is not reef-safe and could damage or consume invertebrates.
