The Nat Geo article (which I read in hardcopy- I don't know the exact contents of the online version. The magazine photos are fantastic) mostly describes the symbiosis between the clownfish and the host anemone., but also mentions how the movie's success has lead to some locations being fished out to supply the aquarium trade.

The Dong-A article mostly describes how the fish are new arrivals to the area, possibly due to increased water temperatures which are making Jeju waters sub-tropical.
both articles are interesting and mostly well written, although the Dong-A briefly reaches Korea Times-quality editing:
|A scuba diver said he witnessed a 30-meter long green sea turtle, which is likely to spend winter in neighboring waters.|
That's one Hell of a sea-turtle!
