I must agree with Atari. I think one of the aspects we encourage in this hobby and on this board is moral responsibility. As such, I think you will see most members encourage you to adopt strategies and approaches which minimize any possible stress or harm to the livestock and help you be a socially responsible fish keeper. For those who use the live fish to cycle their tanks, good luck to you. You make that personal decision with the risk to the fish when you know there are safer alternatives that work as well is not better. Just my thoughts. Ultimately, how you cycle your tank is between you and your conscience. Peace 8)
