Orange Spiny Lobster

The Orange Spiny Lobster (Panulirus argus or related species) is a fascinating marine invertebrate known for its vibrant coloration and spiny exoskeleton. Here’s a detailed guide on its care and habitat requirements:

Habitat & Behavior
Native to tropical and subtropical waters, commonly found in the Caribbean, Florida, and Gulf of Mexico.
Prefers rocky reefs, caves, and crevices where it can hide during the day.
Nocturnal—it comes out at night to scavenge for food.
Aquarium Requirements
Tank Size: Minimum 75 gallons, but larger is preferred for adults.
Water Parameters:
Temperature: 72-82°F
Salinity: 1.023-1.025
pH: 8.1-8.4
Ammonia/Nitrites: 0 ppm (sensitive to poor water quality)
Live Rock & Hiding Spots: Provide caves and crevices for shelter.
Substrate: Sand or small gravel works best.
Diet & Feeding
Omnivorous scavenger—feeds on detritus, dead fish, and invertebrates.
Offer a varied diet including:
Meaty foods (shrimp, squid, mussels)
High-quality sinking pellets
Algae-based foods to balance nutrition
Tank Mates & Compatibility
Semi-aggressive and can become territorial.
Not reef-safe—may eat small fish, crabs, shrimp, and even corals.
Best kept with larger, non-aggressive fish (e.g., tangs, triggers).
Avoid keeping with slow-moving or small tank mates like gobies or ornamental shrimp.
Acclimation Process
Turn off tank lights to reduce stress.
Float the sealed bag in the aquarium for 15-20 minutes to equalize temperature.
Drip Acclimation (Recommended): Slowly add tank water to the container over 45-60 minutes.
Gently transfer the lobster to the tank, avoiding netting to prevent injury.
Molting & Growth
Sheds its exoskeleton every few months to grow.
During molting, it will hide for a few days—do not disturb.
Ensure plenty of calcium and iodine for healthy shell growth.
