Awesom everyone thank you guys alot. Now i was wondering if you guys think they will fair well in my pond. I live in the san francisco bay area which is central california and the temp in summer will reach from 90-100 and in winter the temp drops to around the 50's. Keep in mind i am not talking water temperature. The pond is about 550 gallons and has plenty of rock work and logs and plants inside of it as well as outside of it. I also will be running a creek/waterfall system into the pond as soon as possible. And i have no fish but plan on possibly purchasing a small number of misquitoe fish and letting them reproduce so i can use some as feeders. All info is great thank you guys.
