The Kellogg’s Scorpionfish (Scorpaenodes kelloggi), also known as the Dwarf Scorpionfish, is a small, venomous marine species belonging to the family Scorpaenidae. This species is distributed across the Indo-Pacific region, from East Africa to the Hawaiian, Line, and Society Islands, extending north to Taiwan and south to northern Australia.
Key Information
• Small fish safe: ⚠️ With caution (may prey on very small fish)
• Small invertebrate safe: ⚠️ With caution (may consume small crustaceans)
• Coral safe: ✅ Yes (does not typically harm corals)
• Minimum tank size: 115 litres (30 gallons)
• Adult size: Up to 5 cm (2 inches)
• Diet: Carnivorous, feeding on small fish and invertebrates
• Be aware of: Venomous spines; handle with extreme caution to avoid envenomation
Appearance and Colouration
Scorpaenodes kelloggi exhibits distinctive features that aid in its camouflage:
• Body: Mottled reddish-brown coloration with four diffuse dark bars on the body and another at the base of the caudal fin.
• Fins: Dark bars radiating from the eye and banding on fin rays.
• Size: Reaches a maximum length of approximately 5 cm (2 inches).
Natural Habitat and Behaviour
Scorpaenodes kelloggi is typically found in coralline areas from near shore to the outer reef slope at depths ranging from 6 to 24 meters. It is a benthic species, often hiding under rocks or rubble during the day and actively hunting small fish and invertebrates at night.
Aquarium Care
Due to its small size and specific care requirements, Scorpaenodes kelloggi is rarely kept in home aquariums. However, if encountered, care requirements would likely align with those of similar scorpionfish species:
• Tank Size: A minimum of 115 litres (30 gallons) is recommended to provide adequate space.
• Aquascaping: Incorporate ample hiding spots with rocks and caves to mimic natural habitats.
• Diet: Offer a carnivorous diet consisting of small fish and invertebrates.
• Tank Mates: Select non-aggressive species of similar size to avoid predation or bullying.
Due to their venomous spines, caution is advised during tank maintenance to prevent injury.
