Mombasa Dwarf Lionfish
(Pterois mombasae)
WYSIWYG – Approx. Size: 2.75–3.00 Inches
Maximum Size: Up to 6 Inches

The Mombasa Dwarf Lionfish (Pterois mombasae) is a lesser-seen and captivating member of the lionfish family, known for its intricate patterning, elongated pectoral fins, and subtler coloration compared to its more flamboyant relatives. With mottled shades of tan, cream, and reddish brown, it blends into rocky reef structures while maintaining a commanding, exotic presence. Its smaller size and generally calm demeanor make it ideal for nano predator systems or peaceful FOWLR tanks.

Tank Requirements

Minimum Tank Size: 30 gallons

Environment: Plenty of rock caves and shaded overhangs

Flow: Low to moderate

Lid: Required — lionfish are known to jump when spooked

Mombasa Lions prefer subdued lighting and low-traffic tanks with ample retreat areas. They become most active around dawn and dusk.

Natural Behavior

This ambush predator remains motionless for long periods, waiting to strike unsuspecting prey with a lightning-fast gulp. Despite its venomous spines and intimidating look, it is a relatively calm and slow-swimming resident. Mombasa Lions are usually solitary but can be kept with other peaceful predators if provided enough space.

Diet & Feeding

Carnivorous, requiring a protein-rich diet:

  • Live ghost shrimp or feeder shrimp (initially)

  • Frozen mysis, krill, silversides, chopped squid or clam

  • Use feeding tongs to target-feed and avoid spine contact

Feed 3–4 times per week. It may take time to transition to frozen foods after acclimation.

Tankmates & Compatibility

Temperament: Peaceful to semi-aggressive; predatory toward small tankmates

Reef Safe: With caution — will not harm corals but will eat small fish and shrimp

Best With: Larger gobies, wrasses, hawkfish, and non-aggressive tangs

Avoid small ornamental shrimp, nano fish, or fin-nippers. Mombasa Lions do best in predator-friendly systems with calm, confident tankmates.
