Description
Marbled Scorpionfish (Scorpaenodes sp.)
Overview
The Marbled Scorpionfish is a compact and beautifully patterned ambush predator, displaying mottled shades of red, brown, and cream that provide exceptional camouflage among rocks and corals. Despite its small size, this species has a commanding presence, making it a fascinating addition to a peaceful predatory or species-specific marine aquarium.
Origin
Found throughout the Indo-Pacific region, Scorpaenodes species inhabit rocky reefs, coral rubble, and crevices where they remain motionless, blending perfectly into their surroundings while waiting to ambush prey.
Feeding
A carnivorous predator that feeds primarily on small crustaceans and fish. It may require live foods such as shrimp initially but can adapt to frozen meaty offerings like mysis, krill, or chopped seafood once acclimated. Feed once daily.
Tank Mates
Best suited to peaceful, non-aggressive tank mates too large to be eaten—such as tangs, angelfish, or larger wrasses. Avoid small fish or shrimp, which will be viewed as prey, and avoid overly active or aggressive species.
Aggression
Generally peaceful and solitary. The Marbled Scorpionfish spends much of its time resting and camouflaged, posing no threat to tank mates it cannot swallow.
Experience Level
Recommended for intermediate to advanced aquarists. While hardy, it requires careful feeding and excellent water quality to thrive.
