Plants really slow down fish catching... Long chases are extra stressful.
As fishkeepers, we are torn. I did work with a company that imported wilds, and refused to deal in any endangered or unethically collected species. Customers complained like crazy about the reasonable prices. It simply costs more to deal with small communities of fishers, and to get them shipped in from faraway places. But healthwise? They are so much better than we've come to expect. There are no manufactured blood parrots or glo-fish in that trade as well.
Farmed fish are interesting. I know people who explore for new species, and some try to work with farms by bringing them wild fish so they can establish large populations in the trade. The problem when I have bought even f-1 or f-2 captive bred from those fish has been Mycobacteriosis. Fish tb thrives in crowding, and fish farms must crowd or go bankrupt. Even the good ones have to deal with it.
The bad ones that survive in the race to the bottom pricewise sell awful fish. I used to go the rounds of local stores with a fish veterinarian and he was always excited at the diseases on display. He bought a lot of fish to study their pathogens. We buy them thinking they'll live long lives.
So where do we sit? Certain species go through waves of disease. Waves of disease pass through the market - angels years ago, neons and guppies now, and others to come in the future.
Fish breeding is now unpopular. Even 20 years ago, aquarists living in most reasonably sized centres could stock their tanks with healthy home bred fish, produced by their friends and neighbours. They were as healthy as wild fish, though difficult to breed standards like cardinal tetras rarely were sold.
Small pet shops are always at risk of being snuffed out by corporate chains that offer low prices and push farms to do everything to lower prices even more. Some of the chains would be happy to reduce the hobby to 20 or 30 species, and just sell them. Stores that are good have to deal with higher prices at source and that makes customers run to the cheap. Online sellers don't even have to hide diseases or bad conditions. They can scoop a hundred dead fish out of the tank and sell you the 6 survivors, no questions asked. Our hobby is fouling its own nest, and we are not in a good position.
