Clownfish in 2020s: Host as bottleneck
[154] [more-clownfish-54] In 2020s, the field log for Clownfish is headed “Host as bottleneck.” The figure kept beside that heading is 2003. It is a count or a date from the work, not a rank of the species’ worth. A zoo birthday card does not replace the log. Host anemones entered the same heat ledger as corals.
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.
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. Where is the wild centre of the type?
Eastern Indian and western Pacific reefs -- Andaman to the Philippines and Australia north -- not a Sydney Harbour suburban anemone. Is aquaculture the conservation ending? Captive-bred ocellaris cut some wild take. It does not rebuild bleached hosts or stop cyanide fishing of other reef species sold beside them.
Keep 2020s, “Host as bottleneck,” and 2003 together or the note on Clownfish stops being that year’s record.2020s
