Habitat & Tank Requirements

Natural Habitat: Found on coral reefs, rocky outcrops, and reef flats at depths of 3–130 feet. Typically perches on high vantage points where they survey their territory and watch for prey.

Tank Environment:

• Abundant rockwork with perching spots
• Branching corals or rock structures for perching (live or artificial)
• Moderate open swimming space
• Secure rock formations to prevent toppling
• Various perching heights throughout tank
• Standard reef or FOWLR setup

Water Parameters:

• Temperature: 72–78°F (22–26°C)
• Salinity: 1.023–1.025 specific gravity
• pH: 8.1–8.4
• Ammonia/Nitrite: 0 ppm
• Nitrate: <20 ppm
• Alkalinity: 8–12 dKH

Diet & Feeding

Recommended Foods:

• Fresh/frozen mysis shrimp, brine shrimp, krill (primary diet)
• Finely chopped seafood, fish, squid
• High-quality marine carnivore pellets
• Live blackworms or small feeder shrimp (occasional treat)

• Target feed if kept with aggressive eaters
• Accepts most prepared foods readily

Behavior & Compatibility

Tank Mates:

• Compatible with: Tangs, angelfish, butterflyfish, clownfish, damselfish, dottybacks, gobies, blennies, larger wrasses, most peaceful to semi-aggressive fish
• Caution with: Very small fish (under 2 inches), ornamental shrimp (peppermint, cleaner shrimp may be at risk), other hawkfish in smaller tanks
• Avoid: Nano fish, small gobies, very tiny shrimp species, multiple hawkfish unless tank is 100+ gallons

Social Behavior:

• Perches motionlessly on rockwork surveying territory
• Will dart out to capture passing prey
• Territorial toward other hawkfish and similar-shaped species
• Generally peaceful toward dissimilar tankmates
• May become hand-tame and interactive
• Enjoys perching near top of aquarium for observation

Reef Compatibility: Generally reef-safe with corals and anemones; will not harm sessile invertebrates. May consume small ornamental shrimp (skunk cleaner shrimp usually safe due to size). Safe with fish over 3 inches.

Color & Development

Coloration: Cream, tan, or pale gray base color covered with distinctive red-brown to orange freckles and spots; dark red-brown to black blotches along sides (typically two prominent patches); cirri (hair-like extensions) above eyes; color varies based on geographic origin.

Color Intensity:

• High-quality diet maintains freckle vibrancy
• Stress may cause temporary fading
• Color darkens when displaying territorial behavior
• Geographic variants show different intensity (Red Sea specimens often more colorful)

Size & Growth:

• Juveniles typically available at 2–3 inches
• Moderate growth rate reaching adult size in 2–3 years
