Fuzzy Dwarf Lionfish

Also known as Shortfin Lionfish, Dwarf Fuzzy Lionfish, Dendrochirus Lionfish

The Fuzzy Dwarf Lionfish is one of the most popular and readily available dwarf lionfish species, featuring distinctive “fuzzy” or feathered appearance to the pectoral fin rays and facial tentacles, combined with red, white, and brown banding. This small, hardy lionfish is an excellent choice for aquarists wanting a manageable venomous predator. More readily available and typically less expensive than the Fu Manchu, this species offers similar fascinating behavior in a slightly less ornate package.

Key Features

• Scientific Name: Dendrochirus brachypterus
• Common Names: Fuzzy Dwarf Lionfish, Shortfin Lionfish, Dwarf Lionfish
• Adult Size: Up to 6-7 inches
• Lifespan: 8-12 years with proper care
• Temperament: Peaceful; slow-moving ambush predator
• Reef Compatibility: Reef safe with caution; will eat small fish and shrimp
• Minimum Tank Size: 50 gallons preferred
• Experience Level: Beginner to Intermediate; hardy and venomous spines require care

Habitat & Tank Requirements

Tank Environment: Provide substantial live rock formations with caves, overhangs, ledges, and perching spots. Moderate water flow is preferred. Subdued lighting or provide shaded areas. Nocturnal; needs hiding spots for daytime. Secure decorations.

Water Parameters:

• Temperature: 72-78°F (22-26°C)
• Salinity: 1.020-1.025
• pH: 8.1-8.4
• Good water quality essential

Equipment Recommendations:

• Standard filtration system
• Protein skimmer
• Moderate water circulation
• Subdued or adjustable lighting preferred

These maintain healthy conditions for this predator.

Diet & Feeding

Fuzzy Dwarf Lionfish are carnivorous ambush predators.

Recommended foods include:

• Primary: Frozen silversides, frozen krill, frozen shrimp
• Live foods: Live ghost shrimp, live grass shrimp (for initial training if needed)
• Frozen foods: Frozen marine fish, chopped seafood, frozen prawns
• Variety: Squid pieces, scallops, marine fish
• Training: Usually accepts frozen foods readily; easier than some species

Feeding Frequency: 2-3 times weekly; substantial meals

Special Note: Generally easier to train to frozen foods than some lionfish species. Use a feeding stick to present food. DO NOT overfeed; slow metabolism means feeding 2-3 times weekly is sufficient. Overfeeding causes obesity and health issues.

Social Structure & Compatibility

• Tankmates: Compatible with fish too large to swallow
• Peaceful: Non-aggressive toward appropriate-sized tankmates
• Predatory: Will eat any fish or shrimp small enough to swallow
• Multiple Lionfish: Can sometimes be kept with other dwarf lionfish in larger systems
• Reef Behavior: Safe with corals; will consume ornamental shrimp

Notes & Considerations

• One of the most commonly available and popular dwarf lionfish.
• Distinctive “fuzzy” or feathered appearance to fins and tentacles.
• Red, white, and brown banding creates an attractive pattern.
• Pectoral fin rays have feathered or branched appearance.
• Facial tentacles above eyes add to fuzzy appearance.
• Slightly larger than Fu Manchu but still manageable dwarf species.
• VENOMOUS SPINES: Dorsal, anal, and pelvic spines contain venom.
• Spine stings are extremely painful; severe localized pain and swelling.
• Pain can last hours to days; may cause nausea and systemic effects.
• Medical attention may be necessary for severe reactions.
• Always exercise extreme caution during tank maintenance.
• Never handle with bare hands; use nets or containers carefully.
• Always know the location of the lionfish before putting hands in the tank.
• Hot water immersion (as hot as tolerable) helps denature venom proteins and relieve pain.
• Keep first aid supplies readily available.
• Spines purely defensive; fish not aggressive.
• Slow-moving ambush predator; sits motionless waiting for prey.
• Primarily nocturnal; most active evening and night.
• Often hides in caves or under ledges during bright daylight.
• I will eat ANY fish small enough to fit in my mouth.
• The mouth expands dramatically; it can swallow surprisingly large prey.
• Cannot be housed with small fish: gobies, blennies, small wrasses, small clownfish.
• Will consume all ornamental shrimp without exception.
• Completely safe with all corals; will not nip or damage.
• Can be kept in reef aquariums with large tankmates only.
• Usually accepts frozen foods more readily than some lionfish.
• May still require live ghost shrimp initially to stimulate feeding.
• Can be trained to freeze foods using a feeding stick technique.
• Never feed live goldfish or freshwater feeders (causes liver disease).
• Slow metabolism requires feeding only 2-3 times weekly.
• Overfeeding is the primary cause of health problems and early death.
• Obese lionfish become lethargic and develop fatty liver disease.
• Portion control is absolutely critical for longevity.
• Very hardy once established and on a proper feeding schedule.
• One of the hardiest lionfish species available.
• Relatively disease-resistant; adapts well to aquarium life.
• Can jump or swim near the surface; secure lid recommended.
• Initially may be shy but becomes confident quickly.
• Often perches on rockwork in a characteristic hunting position.
• Uses pectoral fins to corner and herd prey.
• Fascinating predatory behavior to observe.
• Native to Indo-Pacific coral reef regions.
• More readily available than Fu Manchu; typically less expensive.
• Excellent beginner lionfish for appropriate systems.
• Long-lived with proper care and feeding discipline.

Why Choose a Quarantined Fuzzy Dwarf Lionfish?

Purchasing a quarantined specimen from us means you’re starting with a healthier, properly acclimated lionfish. All fish are observed, treated as needed, and critically, trained to accept frozen foods before sale. Many lionfish require live foods initially, but our specimens are already weaned to frozen silversides and other prepared foods, ensuring proper nutrition and convenience. Proper quarantine ensures optimal health and disease-free introduction. This provides the strongest foundation for long-term success with this popular and hardy species. Always exercise extreme caution around venomous spines.
