There are really different philosophies and belief systems in the hobby - funny for a pastime that just seems to be a pastime.
A lot of aquarists just won't learn the basic science (what's a species? (tough question...) What are the habitats our fish come from? Why does the water matter? How do fish bodies work?) and I think that takes away from the value of fish to us. I worked in an industry where for the big players, fish were called 'units' and the differences between them could be simply prices. If you hybridize, you can demand higher prices. If you can reduce the number of species brought in from wild sources, then you don't have to deal with local fisher families and the infrastructures they create.
The hobby has also cultivated pain, for money. A balloon fish has compressed guts and a possibly painful case of scoliosis, but if we don't look into it, it makes them cute. The fish is ornamental.
All of this makes me very skeptical of any hopes for ethics with these new technological wrinkles. There will always be ethical people, and always crooks. And there will be great advances. In 2 weeks I'll be on a fish collecting expedition that will gather fish for study, which will probably end with AI application DNA work. It can help us learn about our world.
Someone will use it invent fake species. Fraud is just too tempting for some people, even if they use an app or two to make themselves feel smarter than the 'suckers'. You know that. But others'll use it to learn more about nature - something we are really behind on understanding.
