Habitat & Tank Requirements

Natural Habitat: Entirely captive-bred, Longfin Ocellaris Clownfish are selectively bred variants derived from Indo-Pacific ancestors. This specialized morphology is purely a product of selective breeding.

Tank Environment:

• Abundant live rock with caves and crevices (avoid sharp edges damaging fins)
• Host anemone (Bubble Tip preferred) recommended but not required
• Moderate, gentle water flow (strong flow damages flowing fins)
• Mature, stable aquarium (3+ months established minimum)
• Open swimming areas with minimal sharp surfaces
• Secure territory establishment space

Water Parameters:

• Temperature: 74–78°F (23–26°C) (consistency critical)
• Salinity: 1.023–1.025 specific gravity
• pH: 8.1–8.4
• Ammonia/Nitrite: 0 ppm
• Nitrate: <20 ppm (lower preferred for fin health)
• Alkalinity: 8–12 dKH

Essential Equipment:

• Premium protein skimmer
• High-efficiency biological and mechanical filtration
• Adjustable water circulation (lower flow to protect fins)
• Regular water changes (15–20% biweekly minimum)
• UV sterilizer (recommended)
• Temperature controller (maintains stability)

Diet & Feeding

Longfin Ocellaris Clownfish require premium nutrition to maintain health and support flowing fin structure.

Recommended Foods:

• Frozen Foods: Premium mysis shrimp, enriched brine shrimp, finely chopped krill, copepods
• Pellets/Flakes: High-quality marine pellets, color-enhancing formulas
• Plant Matter: Spirulina flakes, nori pieces, marine algae
• Live Foods: Occasional brine shrimp (beneficial for conditioning)
• Prepared Mixes: Premium clownfish formulas, enriched marine cuisine

Feeding Schedule:

• Feed 2–3 times daily in appropriately sized portions
• Offer variety to maintain optimal health and coloration
• Include foods rich in carotenoids and omega fatty acids
• Supplement with vitamin-enriched foods weekly
• Ensure adequate protein for fin development

Fin Health Nutrition:

• High-quality protein sources support fin structure
• Omega fatty acids essential for fin ray health
• Vitamin and mineral supplementation important
• Consistent feeding schedule supports development
• Carotenoid-rich foods for coloration

Note: Premium nutrition is essential for maintaining vibrant coloration and supporting dramatic fin development.

Behavior & Compatibility

Temperament:

• Peaceful but can be territorial around anemone
• Confident and bold once established
• Interactive and curious with tank inhabitants
• More active swimming than some clownfish
• Graceful movement enhanced by flowing fins

Tank Mates:

• Compatible with: Peaceful tangs, wrasses, gobies, blennies, cardinalfish, peaceful dottybacks, chromis, anthias
• Caution with: Large aggressive fish, triggers, lionfish, fin-nippers
• Avoid: Aggressive species that might chase or damage flowing fins

Reef Compatibility:

• Reef-safe: Will not harm corals or invertebrates
• Compatible with all coral types
• May interact gently with anemones
• Excellent reef system addition

Anemone Hosting: Longfin Ocellaris will host in anemones but thrive without them. Recommended:

• Bubble Tip Anemone (Entacmaea quadricolor)—preferred
• Carpet Anemone (Stichodactyla mertensii)
• Magnificent Sea Anemone (Heteractis magnifica)

Acclimation & Care Tips

Initial Acclimation:

• Extended drip acclimation over 2–3 hours
• Dim tank lights for first 48 hours
• Provide anemone or multiple secure hiding spots
• Introduce to mature, stable aquarium
• Handle carefully to avoid fin damage during transport
• Usually feeds within 12–24 hours

Health Considerations:

• Hardy once acclimated despite delicate fins
• Moderately susceptible to parasites (precautions essential)
• Quarantine for 3–4 weeks before display tank addition
• Monitor closely during acclimation
• Maintain pristine water quality
• Watch for fin damage from transport or tank interactions

Fin Care and Protection:

• Avoid sharp rockwork edges that damage flowing fins
• Ensure gentle water flow doesn’t shred fin rays
• Monitor for fin damage during acclimation
• Avoid aggressive tankmates that chase or bite
• Gentle handling during water changes essential
• Clean water quality supports fin regeneration

Signs of Healthy Specimen:

• Active, graceful swimming behavior
• Vibrant orange coloration with clear white bands
• Bright, alert eyes
• Eager, consistent feeding response
• Smooth, intact flowing fins (undamaged ray)
• No visible parasites or lesions
• Interaction with anemone (if present)
• Confident behavioral display within 2–3 days
• Dramatic fin extension during swimming

Color & Development

Adult Coloration:

• Body: Vibrant orange coloring
• White Bands: Three white vertical bands bordered by black
• Fins: Elongated, flowing rays creating dramatic extensions
• Pattern: Classic clownfish three-bar enhanced by extended finnage

Fin Development:

• Dorsal Fin: Elongated rays extending beyond body length
