Coral Banded Shrimp – Decapoda sp.

Overview:
Coral Banded Shrimp (Stenopus hispidus) is a striking reef invertebrate best kept in a mature, stable marine aquarium where water quality and shelter are consistent. Provide plenty of rockwork with tight crevices and overhangs; they spend much of the day tucked away and become more active at dusk. Stable parameters matter more than chasing exact numbers: keep salinity around 1.024–1.026, temperature 24–26°C (75–79°F), pH 8.1–8.4, and low nitrate and phosphate. Moderate flow and good oxygenation help, but avoid blasting their preferred caves. They molt regularly; during and just after a molt they are soft, vulnerable, and more likely to hide. Iodine is often discussed, but routine dosing is not required if you perform regular water changes and avoid extremes; focus on consistency and adequate nutrition instead.

Compatibility:
This species is territorial, especially toward other shrimp. Keep one per tank unless you have a confirmed male–female pair in a sufficiently large aquarium with multiple separate shelters; otherwise fighting is common. They can harass or kill smaller decorative shrimp (peppermint, cleaner shrimp, sexy shrimp) and may prey on very small fish or slow, bottom-resting fish at night, particularly in cramped systems. They typically ignore most reef-safe fish that are larger and active, but avoid housing with aggressive predators (lionfish, triggers, large wrasses, hawkfish, groupers) that may eat them. With corals they are generally safe, though a hungry individual may steal food from LPS during feeding. They can coexist with many snails and larger hermits, but may take very small crustaceans.

Health and Quarantine:
Most issues trace back to unstable salinity/temperature, elevated nitrate, copper exposure, or stress around molting. Never use copper-based medications in any system containing shrimp. Watch for failed molts, lethargy, missing limbs, or persistent hiding beyond normal behavior. Provide ample hiding places, keep alkalinity and salinity steady, and minimize sudden changes during water changes. Quarantine is best done in a dedicated invertebrate-safe tank (no copper) for 2–4 weeks to observe for injury, bacterial issues, and to ensure strong feeding. Acclimate slowly (drip acclimation) and keep handling to a minimum, especially near molting.

Coral Banded Shrimp are omnivorous scavengers and opportunistic predators. Feed small meaty marine foods 2–3 times per week (more often in newer tanks with less natural food). Suitable options include thawed mysis, finely chopped shrimp, clam, squid, krill, and quality sinking pellets formulated for marine carnivores. Target feeding with tongs or a pipette near their cave reduces food theft by fish and helps ensure the shrimp eats well. Remove uneaten food to prevent nutrient spikes. They may pick at detritus and leftovers, but they should not be relied on as “cleanup” for heavy feeding.

Pellets Leftover Fish Food Finely Chopped Seafood
Coral Banded Shrimp are bold, territorial invertebrates that typically establish a permanent home within a cave, overhang, or rock crevice. They spend much of their time perched at the entrance of their chosen shelter with their large claws extended, defending the area from other shrimp and small invertebrates. While they may scavenge for leftover food, they are more predatory than cleaner shrimp and will actively seize passing food items. They are generally peaceful toward fish but can be aggressive toward other shrimp, especially similar species, if space is limited. Their striking posture and defensive behavior make them highly visible despite their tendency to remain close to shelter.

FAQ

Frequently Asked Questions

About the Coral Banded Shrimp

  • Why is my Coral Banded Shrimp aggressive toward other shrimp and invertebrates?
    Coral Banded Shrimp are naturally territorial and far more aggressive than most commonly kept cleaner shrimp. In the wild, they defend caves and overhangs where they wait to ambush passing food. In aquariums, this translates to strong territorial behavior, especially toward other shrimp species, smaller crabs, or similar-sized invertebrates. Once established, they may actively chase or attack competitors that wander too close to their chosen area. This behavior is not a sign of poor health but rather an instinctive response to limited territory. Keeping only one Coral Banded Shrimp per tank or providing extensive rockwork with clearly separated caves helps reduce conflicts.
  • Can Coral Banded Shrimp be kept with cleaner shrimp like Skunk or Fire Shrimp?
    In most cases, this is not recommended, especially in smaller or moderately sized tanks. Coral Banded Shrimp often view other shrimp as competition and may harass or kill them, particularly at night when other shrimp are more vulnerable. In very large aquariums with abundant hiding places and clearly defined territories, coexistence is sometimes possible, but it is unpredictable. If mixing shrimp species, careful observation during the first several weeks is essential.
  • Will a Coral Banded Shrimp attack fish?
    They do not actively hunt healthy fish, but they are opportunistic predators. Slow-moving, very small, or weakened fish that rest near the shrimp’s cave may be grabbed, especially at night. Most losses attributed to Coral Banded Shrimp involve fish that were already stressed, injured, or sleeping too close to the shrimp’s territory. Choosing appropriately sized, active fish and avoiding bottom-sleeping species reduces risk.
  • Why does my Coral Banded Shrimp wave its claws constantly?
    The raised, open-claw posture is a natural defensive display. Coral Banded Shrimp use this posture to warn potential threats and establish dominance over their territory. This behavior becomes more pronounced when new tank mates are introduced or when the shrimp feels crowded. It is normal and does not indicate stress unless paired with frantic movement or refusal to eat.
  • My Coral Banded Shrimp disappeared after molting. Should I be concerned?
    After molting, Coral Banded Shrimp often retreat deep into rockwork while their exoskeleton hardens. This hiding period can last several days. As long as water conditions remain stable and food is available, the shrimp will usually reemerge once it feels secure. Finding an empty shell does not mean the shrimp has died, as molts are frequently mistaken for deceased animals.
