Michael37090, That's good that you have something close like that. If I may offer a suggestion to you on this: Use this as a true educational experience and positively ID every fish you transfer. Some are more obvious than others but they may be certain species present that would (in their largest/larger sizes) be unwanted or less than beneficial to your pond.
I would love to have something like that close to me as I enjoy looking and learning about the smaller subjects that are more easily caught. I learn as I go, with the help of several here. Be Cautious in what you transfer and be sure.. If not sure, put a specimen in a ziplock and post it here. just 2 of an undesirable species can wreck what may otherwise be a great experience.
