The care below is clownfish-level guidance from our species hub, sourced to Merck Veterinary Manual — Aquarium and Pond Fish and RSPCA — Fish care.

How long do clownfish live
Clownfish live 6–10 years, sometimes longer, in stable marine systems. They are sensitive to rapid salinity and temperature swings and to poor water quality (marine fish show stress fast). The usual failures are an uncycled tank, unstable salinity, and disease (marine ich / cryptocaryon) in unquarantined fish. Patience with the cycle pays off.
Saltwater baseline
A pair needs at least a 20–30 gal (75–115 L) mature reef or fish-only tank; more is better. Salinity ~1.020–1.026 sg, temperature 75–80°F (24–27°C), strong filtration, and protein skimming help. Test salinity and ammonia/nitrite/nitrate regularly. Marine systems are less forgiving — stability beats heroics.
