Red Angler, Super – Antennarius pictus

Introduction to Red Anglerfish (Antennariussp.)

The Red Anglerfish, often referred to as a “Frogfish,” is one of the most unique and specialized predators in the saltwater hobby. Known for its vibrant red coloration and incredible camouflage, this species blends seamlessly into rockwork and coral structures. What sets anglerfish apart is their built-in “fishing lure” (illicium), which they use to attract prey before striking with lightning speed. Their unusual movement, often walking along surfaces using modified fins, makes them a standout centerpiece in species-specific setups.

Care Requirements

Care Level:Moderate to Difficult
Minimum Tank Size:30+ gallons
Aquarium Setup:Requires stable rockwork, low to moderate flow, and a species-focused environment

Red Anglers are not active swimmers and prefer to perch rather than roam. A calm tank with minimal competition and secure rock structures is ideal.

Diet & Nutrition

Red Anglerfish are carnivorous ambush predators that feed on live or meaty foods.

Diet:Carnivorous – Feeds on fish and crustaceans

Recommended Foods:

• Live or frozen shrimp
• Small feeder fish (used sparingly)
• Silversides or other meaty marine foods

They can often be trained to accept frozen foods using feeding tools, but initial feeding may require live prey.

Lifespan & Growth Rate

Lifespan:3–5+ years
Growth Rate:Moderate – Typically reaches 4–6 inches depending on species

They grow steadily but remain relatively sedentary throughout their lives.

Temperament & Compatibility

Temperament:Predatory
Reef Safe?No – Will consume fish and invertebrates that fit in its mouth

Red Anglers should be kept alone or with extreme caution. Any tankmate small enough to be swallowed will eventually become food.

Common Challenges & Considerations

• Predatory Behavior:Will eat tankmates, often surprisingly large ones
• Overfeeding Risk:Prone to obesity if fed too frequently
• Feeding Transition:May require live food before accepting frozen options
• Water Quality Sensitivity:Requires stable, clean water despite low activity
• Limited Movement:Not a typical “active” display fish

Water Conditions

Temperature:75–77°F
dKH (Alkalinity):8–12
pH:8.1–8.3
Specific Gravity:1.024–1.026
