Scorpaena Plumieri - The Spotted Scorpionfish


Overview

  • Commonly known as the Spotted Scorpionfish.
  • Native to the Western Atlantic, including the Caribbean, Gulf of Mexico, and coastal waters of North and South America.
  • Recognized for its textured body, excellent camouflage, and venomous spines.
  • A slow-moving but highly effective ambush predator.

Feeding

  • Carnivorous diet, primarily feeding on small fish, shrimp, and crustaceans.
  • Prefers live prey but can be trained to accept frozen foods such as silversides and squid.
  • Requires infrequent but substantial feedings due to its slow metabolism.
  • Feeding should be done using tongs to avoid accidental contact with venomous spines.

Habitat

  • Typically found in rocky reef environments, coral outcroppings, and sandy seabeds.
  • Prefers stable water conditions with moderate to low currents.
  • Requires a minimum 75-gallon tank with ample rock formations for hiding.
  • Best kept in a dimly lit environment to match its natural habitat.

Fish Care

  • Optimal water temperature: 72-78°F (22-26°C).
  • Ideal pH level: 8.1-8.4, with a specific gravity of 1.020-1.025.
  • Requires a well-maintained aquarium with strong filtration.
  • Venomous spines require careful handling; avoid direct contact.
  • Keeping water parameters stable is essential to prevent stress-related illnesses.

Compatibility

  • Solitary and should be housed with caution.
  • Compatible with large, non-aggressive fish that do not fit in its mouth.
  • Should not be housed with small ornamental fish or invertebrates, as they may be eaten.
  • Does best in species-specific or predator-based setups.

Aquarium Behavior

  • Prefers to remain motionless, blending into its surroundings.
  • Relies on ambush hunting, waiting for prey to come within striking distance.
  • Moves slowly but can exhibit rapid lunging behavior when feeding.
  • Providing a well-structured environment with ample hiding spots enhances its natural behavior.
