ORA (Oceans, Reefs & Aquariums) operates a state-of-the-art aquaculture facility producing captive-bred marine fish, aquacultured coral, and tank-raised invertebrates. ORA's mission centers on reducing pressure on wild reefs through aquaculture while delivering hardy, established livestock to the hobby.
Beyond captive breeding, ORA maintains an extensive named-cultivar coral catalog that has shaped the SPS reefkeeping community for two decades. Many of the most-traded named Acropora and Montipora lineages in the hobby originated at, or were widely propagated from, ORA stock.
For coral keepers: ORA was one of the first commercial operations to systematically aquaculture LE Acropora at scale. Many "ORA-named" cultivars became hobby standards because they were reliably available year-round through ORA's facility, where wild collection had been the only prior path.
For fishkeepers: ORA's captive-bred clownfish program (alongside Sustainable Aquatics, Proaquatix, and Sea & Reef) created the modern aquacultured marine fish industry. Hardy, eat-prepared-foods, accept-tankmates clownfish exist as a hobby norm today because of work that started at ORA decades ago.
ORA stock circulates through hundreds of retail vendors across North America. Multiple founding-cohort Fast Aquatics vendors carry ORA aquacultured stock and named-cultivar Acropora frags. Verified ORA lineage will be a future Fast Aquatics vendor badge.
Ora care recommendations cross-checked against the following authoritative references and our internal vendor + breeder database.
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.
