Clark's Clownfish
Amphiprion clarkii
Animalia›Chordata›Actinopterygii›Perciformes›Pomacentridae
📍 Indo-Pacific, from Persian Gulf to Western Pacific
Widest-ranging clownfish in the world. Bold black body with two or three white bars and vivid yellow-orange fins. Highly adaptable to a range of host anemones. Hardy, captive-bred specimens available.
Care Guide
Diet
Clark's Clownfish are omnivores that thrive on a varied diet of high-quality marine flakes, small pellets, and frozen foods like brine shrimp, mysis shrimp, and copepods. Feed once daily in small portions that can be consumed within 2-3 minutes. Supplement occasionally with algae-based foods and blanched vegetables to support overall health and coloration.
Behavior
Bold and curious, Clark's Clownfish are highly active swimmers that spend much of their time exploring the tank and interacting with host anemones. They exhibit semi-aggressive behavior, particularly during breeding season or when defending territory around their anemone host. These fish are social within their own species when tank-raised together from juveniles, though aggression can develop in smaller tanks.
Breeding
Breeding in captivity is moderately difficult but achievable with proper conditioning and a dedicated breeding setup. Pairs will lay eggs on flat surfaces near their host anemone; eggs hatch in 7-8 days and require specialized rearing of planktonic larvae. Success requires excellent water quality, live food cultures for fry, and patience through the larval stage.
Tank Mates
Similar care requirements and peaceful coexistence possible, though some territorial disputes may occur
Beneficial symbiotic relationship; shrimp clean parasites and debris from clownfish
Compatible with clownfish; occupies different tank zones and provides cleanup services
Small, peaceful fish that provides cleaning services without competing for resources
Herbivorous tang that occupies different feeding niche; requires adequate space
Common Diseases
Ich (White Spot Disease)
White spots on body and fins, rapid breathing, rubbing against surfaces, lethargy
Raise temperature gradually to 28-29°C, maintain excellent water quality, use copper-free ich medication or UV sterilization; quarantine infected fish
Marine Velvet (Oodinium)
Fine golden or rust-colored dust on body, rapid gill movement, loss of appetite, clamped fins
Increase aeration, lower salinity slightly if tolerated, use copper-free treatments or UV sterilization; quarantine and observe closely
Fin Rot
Frayed or deteriorating fin edges, discoloration at fin bases, progressive fin loss
Perform large water changes, improve water quality and reduce stress, use antibiotic medications if bacterial; ensure adequate filtration
Bacterial Infection
Open sores, cloudy eyes, swollen belly, loss of appetite, color fading
Quarantine affected fish, maintain pristine water conditions, use broad-spectrum antibiotic treatments; address underlying stressors
