Pet clownfish (like most marine species) are mostly wild caught - https://en.wikipedia.org/wiki/Amphiprioninae#In_the_aquarium https://en.wikipedia.org/wiki/Amphiprioninae#In_the_aquarium I believe Clownfish and blue tangs are all Least Concern. There is some concern that they might be threatened by overfishing as pets, but I'd say a much more realistic threat is habitat destruction (due to coral bleaching and pollution degrading the ability of damaged reefs to bounce back). Fish takes can be essentially embassies for the reef, and can be used to educate people on how important protecting the habitat is. Hell, even for pandas, their status as zoo animals (and a national symbol) encourages China to protect their wild habitat (it's not like China doesn't have demand for more land).
