After buying two species of dwarf cichlids that were wild caught, I realised that I wasn't comfortable with the idea and felt rather guilty that they had been taken out of their natural environment. Because of that I'm going to try and ensure that I personally will never buy wild caught fish again.
Saying that, I do understand that it is needed for our hobby to continue and keep stocks healthy. It's of course up to each individual, and I don't judge anyone else for having wild caught fish, I just don't feel right buying them any more.
I was actually kind of thinking about trying to breed my Laetacara Araguaiae (one of my wild caught species), and try and up the numbers of these fish available so that less need to be caught in the wild. Although I do appreciate it's an enormous task and have no idea if people would be actually interested in that species, or if it's even possible to breed them.
