Amphiprion ocellaris is the "false percula" - so named because for decades it was confused with Amphiprion percula. The two are distinguished primarily by dorsal spine count (ocellaris has 11, percula has 10) and the thickness of black banding around the white stripes.
Ocellaris is the foundation species of the captive-bred clownfish industry. Sustainable Aquatics, Proaquatix, ORA, Bali Aquarich, and Sea & Reef have collectively produced millions of captive-bred ocellaris over the past two decades, generating dozens of distinct color and pattern lineages along the way.
Ocellaris are reef-safe and peaceful by clownfish standards. They form mating pairs and may bond with anemones (Bubble Tip, Carpet, Long Tentacle). They tolerate most tankmates but should not be kept with other clownfish species except in extremely large systems.
Captive breeding has produced dozens of distinct ocellaris lineages. Each has its own dedicated page on Fast Aquatics.
Ocellaris are sequential hermaphrodites: all juveniles develop as males, the largest pairs into the dominant female. Captive breeding requires a stable bonded pair, regular high-quality feeding (mysis, brine, frozen Cyclop-eeze), and a flat substrate (terra cotta pot, slate tile) for egg deposition. Eggs hatch 7-10 days after laying. Larvae require live rotifers and copepods through metamorphosis.
Whatever specific topic brought you here, four fundamentals govern long-term aquarium success: water quality, parameter stability, biological filtration, and species-appropriate husbandry. Skip any one and the others struggle to compensate.
Water quality: ammonia + nitrite at zero, nitrate under 30 ppm freshwater + 10 ppm reef. Test weekly with API or Salifert kits. Use our water parameter checker to score your readings against your tank type.
Parameter stability: stable wrong parameters beat fluctuating ideal parameters. Most fish tolerate a wide pH range if it's stable. Sudden swings of 0.4+ pH or 5+°F kill fish faster than chronic suboptimal values. Use temperature controllers (Inkbird) + automated dosing for consistency.
Biological filtration: the bacterial colony on your filter media + rock + substrate is the engine. Never replace all media at once. Use our filter turnover calculator to size correctly.
Species-appropriate husbandry: research adult size, territoriality, diet, and tankmate compatibility before purchase. Use our tank stocking calculator + compatibility guides.
How long does an aquarium take to set up? 4-6 weeks for full cycling + first stocking. Use our cycle ETA calculator + how long does cycling take.
What's the best aquarium for beginners? 20-gallon long. Big enough for parameter stability, small enough for budget + space. See beginner picks.
How often should I do water changes? 25-30% weekly. See water change frequency Q&A + water change calculator.
Why does my fish keep dying? 5 leading causes: uncycled tank, wrong species pairings, no quarantine, undersized tank, neglected water-change schedule. See full diagnosis.
