One of the problems with maintaining a species in captivity is that after
many generation it is no longer what the wild fish was. An aquarium is not
the wild, the same stress are not present evolution will take place. If you
came to the Ann Arbor convention you saw Jim Langhammers talk on goodeids,
Jim maintains several goodieds that are extinct in the wild. They no longer
look like the wild caught fish. If we released aquarium fish like zebra
danios back into the wild they would not necessarily compete like their wild
cousins. If you have become extinct in the wild,but survive only live in
captivity, it is still a great loss. All efforts must be made to maintain
species in the wild. Also several of the goodied species had many captive
colony's but people and institutions lost interest and some are down to only
one or to captive colonies on earth.
