Description

A cryptic, bottom-dwelling predator known for its venomous spines and camouflage mastery. The Yellowspotted Dwarf Scorpionfish blends into live rock with mottled red, brown, and orange tones punctuated by subtle yellow-blue spotting. Incredibly still and secretive, it’s a specialist species for nano-predator displays.

Core Details

Highlights

Care Level

0

/ 10

Requires species-specific care due to venom, sedentary habits, and live feeding needs. Best for experienced marine keepers.

Environment Impact

0

/ 10

Occasionally wild-collected in small numbers. Minimal large-scale demand, but delicate reef harvesting should be monitored.

Origin
Native to the Indo-Pacific, particularly coral-rich zones from the Red Sea to the Philippines and Papua New Guinea. Prefers rubble-strewn reef flats and lagoons with rich hiding cover.

Visual & Behavioral Appeal
Nearly invisible when motionless, this fish masters stillness and mimicry. Small yellow or bluish spots and complex textures add beauty up close. Ambush-style movement and slow hover-swimming offer a unique dynamic in contrast to active species.

Purpose
Serves as a solitary predator in nano or specialty reef tanks. Adds intrigue and realism to cryptic reef setups, mimicking wild microhabitats.

Importance
An excellent subject for species-focused nano displays or educational exhibits on reef camouflage and predation. Encourages precision aquascaping and observational patience.

Included Resources
Requires high-quality live rock, crevices, rubble piles, and low flow. Secure lid is mandatory due to rare but possible darting. Feeding tools and isolated feeding zones are essential.

Best Use Cases
Nano reefs (20+ gallons), species-only displays, or predator-focused pico tanks. Often kept in coral-focused tanks without mobile inverts.

Conservation Context
Not currently at risk, but sensitive to habitat degradation. Wild collection should be ethical—avoid undersized specimens or sellers without sourcing transparency.

Ideal Aquatic Species
• Should be kept alone or with:
 – Micron gobies
 – Non-aggressive blennies
 – Pipefish (if size-compatible)
 – Soft corals and hardy LPS
 – NO shrimp, crabs, or ornamental inverts

Region (A)
• Latitude: 9.0723° N

(Surigao del Sur, Philippines – coral rubble slope zones)

Region (B)
• Latitude: -6.3149° S
• Longitude: 143.9555° E
(Papua New Guinea – shallow coral lagoon edges)
