The French Angelfish thrives in the warm, tropical waters of the western Atlantic Ocean. Understanding their natural environment provides crucial insights for both conservation efforts and successful aquarium keeping.

Geographic Range

French Angelfish inhabit a vast range throughout the tropical western Atlantic:

Region	Specific Locations	Population Density
Caribbean Sea	Bahamas, Jamaica, Barbados, Trinidad	High
Gulf of Mexico	Florida Keys, Texas Coast	Moderate
South America	Venezuela, Guyana, Brazil	Moderate
Central America	Belize, Honduras, Costa Rica	High

Preferred Environmental Conditions

These magnificent fish show strong preferences for specific habitat types:

Depth Requirements:

• Juveniles: Shallow waters 3-15 feet deep

Salinity	1.020-1.025 specific gravity	Gradual changes only
pH	8.1-8.4	Monitor daily
Ammonia	0 ppm	Any detection requires immediate action
Nitrite	0 ppm	Toxic to angelfish
Nitrate	<20 ppm	Weekly water changes essential

Equipment and Filtration

French Angelfish produce significant bioload, requiring robust filtration systems:

Essential Equipment:

• Protein skimmer rated for 2x tank volume
• Canister filter with mechanical and biological media
• UV sterilizer to control pathogens
• Powerheads for water circulation
• High-quality lighting for live rock health

Compatible Tank Mates

Selecting appropriate tank mates requires careful consideration of size, temperament, and feeding requirements:

Excellent Companions:

• Large tangs (Yellow, Purple, Sailfin)
• Groupers and bass species
• Large wrasses
• Triggerfish (with caution)
• Moray eels

Avoid These Species:

• Small fish that could become prey
• Aggressive territorial fish
• Other angelfish species (territorial conflicts)
• Invertebrates (will be eaten)

Feeding Requirements

French Angelfish are omnivores with complex nutritional needs:

Daily Diet Should Include:

• High-quality marine flakes or pellets
• Fresh or frozen mysis shrimp
• Chopped seafood (shrimp, scallops, fish)
• Marine algae and seaweed
• Vitamin-enriched foods

Feeding Schedule:

• Juveniles: 3-4 small meals daily
• Adults: 2 larger meals daily
• Variety: Rotate food types to ensure nutritional balance

Health Considerations and Common Issues

French Angelfish can be susceptible to several health problems in aquarium settings:
