FreedomFighter, that is true of course, and it had crossed my mind and is probably the main reason why I've never seriously considered breeding them.
Just to put this into some perspective.
People taking the fish from the wild and domesticating them, this is exactly what happened with Dogs and Cats. Wild species taken and kept in the confines of a camp/building.
And I presume you have no quarrel over the purchase of a dog or cat?
Not trying to start anything, I just think it's a valid point worth saying, but at the same time I completely understand your side of the discussion and to some extent, agree with it.
I think I'm personally uncomfortable with wild caught fish (or any wild caught exotic pet for that matter) for two reasons really. Dogs and cats were domesticated thousands of years ago, and there's nothing I can do about that. It's not like if I want a German Shepherd or a poodle I have to ask someone to go and catch me one from the wild and force it to live in a totally alien environment, as dogs and cats have adapted over the years to live with us. (Also, just as a side note, I would never buy a dog or a cat, I will always have rescues, and would love to be able to get "rescue fish", but can't seem to find any >.<).
So basically if I can get a fish that is captive bred, then why should I take a wild caught specimen from it's natural environment just for my viewing pleasure (as I don't breed my fish).
Secondly I'm vegan, (and probably from the view point of most other vegans shouldn't even be keeping fish) and believe all life is equal. For me personally (and just to make this clear so that people hopefully don't take my comment the wrong way, I don't expect/demand anyone else to hold the same views), I would feel just as guilty about taking a fish from the wild as I would a macaw, or a bearded dragon, etc.
I realised this after I bought my two wild caught cichlid species, and this is why I have decided personally never to buy wild caught fish again.
So at the end of the day I guess I agree with both sides of the argument. I realise that it is essential for both the hobby and some species to survive by catching wild fish and introducing new genes into the captive stocks. As stated already by several other people, as long as there are huge numbers of the species, then fair enough. I do think however that more procedures need to be put in place to ensure that fish species don't become endangered or indeed extinct.
But because I won't be breeding my fish, I don't see the need for me to buy wild caught specimens
Hope this doesn't come across the wrong way, as I'm really tired and slightly tipsy And whoa, sorry for such a long post ^^'
