Taxonomy
Named from the reef
19th-century types came from a trade that already moved colourful fish.
Milestones in order. This is history, not a weekly activity grid.

Quick answers
Is Nemo an ocellaris or a percula?
Pixar Nemo is styled on Amphiprion ocellaris (this atlas type). Shops still mix ocellaris and percula under one common name.
How does sex change work?
A group is a female, a breeding male and non-breeders. If the female dies, the male changes sex. The film missing-mother plot skipped that rule.
Did Finding Nemo increase wild take?
Several trade analyses reported a demand spike after 2003. Captive-bred ocellaris later absorbed much of the legal market in the US and EU.
Why do anemones not sting their fish?
The fish mucus lacks the cues that trigger nematocysts, and acclimation behaviour matters. It is not a cartoon handshake.
What happens when a host bleaches?
Fish may linger on a dying anemone and then vanish from that site. Reef heatwaves are a housing crisis for the genus.
Are clownfish good parents in the film sense?
Males tend the nest of demersal eggs. The biology is paternal care, not a transoceanic search.
The clownfish did not enter English as a finished emblem. Hunts, films, listings and field stations rewrote the animal on a dated clock.
This chapter keeps ten timeline points, five eras and three milestones so a later translation can hold the same years.
Where it began
Pomacentrid radiationIndo-Pacific reefs
Timeline
1830Cuvier Amphiprion
Anemonefishes entered European systematics from Indo-Pacific collections.
1960sMariculture trials
Early captive breeding of clownfish became a tropical-aquarium footnote.
1972Allen anemonefish monograph
Gerald Allen work organised the genus for field and trade.
1990sCyanide-fishing exposes
Philippine and Indonesian capture methods hit aquarium-trade press.
2003Finding Nemo
Pixar film made ocellaris the most recognised reef fish on Earth.
2004Nemo-effect papers
Trade and education journals began arguing over capture spikes.
2008Captive-bred mainstream
US chain stores shifted many ocellaris SKUs to tank-raised.
2016Finding Dory
A sequel reopened the do-not-release-pets PSA that aquariums had begged for in 2003.
2016GBR bleaching
Host anemones sat inside the same heat event as corals.
2020Heatwave repeats
Successive bleaching years made host availability the new limiting story.
The eras
1960s-90s
Tank and cyanide
Breeding existed; wild cyanide still stocked much of the shelf.
2003-08
Nemo years
A film outsold every field guide; captive breeding scaled in response.
2016-
Dory and bleach
A sequel PSA met a hotter Coral Triangle.
2020s
Host as bottleneck
Anemone survival, not cartoon fame, sets the wild future.
Milestones
Finding Nemo
2003A children film became a capture-and-education case study.
Tank-raised SKUs
2008-Legal US/EU ocellaris shifted heavily to aquaculture.
Bleaching overlap
2016-Host anemones entered the same heat ledger as corals.
Reading clownfish history beside the resilience score keeps a recovered stock from standing in for a threatened cousin.
