Being new to the list, I have to ask--what do you do with a gar or whatever
that grows into a tank buster? My own policy has been never to release
anything that I have taken into captivity, but it would be awful to have to
euthanize a fish that has gotten too big to keep. Do you-all have an
official or generally agreed upon policy regarding release of natives?
