No one should be buying zebra plecs in ones and twos unless they are adding to a group to start a breeding colony. By keeping them as trophy specimins rather than for breeding purposes you are removing that fish from the captive gene pool and reducing numbers that would otherwise be producing fry. It is now illegal to import zebra plecs from the wild and their habitat is under threat of destruction by the building of a hydroelectric dam, when the ones we have in captivity are gone there will be no more.
