Best choice- Tank Raised, Second best- Hand/net caught, Worst- Cyinide fishing. There was a good article in Scientific America a while ago about cyinide fish. They said that less like 7% persent will ever make it to a home aquarium. Talk to your lfs to find out how they got there fish. If you buy a fish that was used by cyinide fishing, you'd only be supporting doing that in the long run, so just dont buy it.
