I have been considering getting a small group of black moore gold fish. I was wondering if anyone had first hand experience of how temperature sensitive these guys are. I want to get some smaller stock -4 fish, 2 1/2"- 3"- and start them in a 125gal stock tank outside this summer. My question is can they tolerate the summer heat with the water reaching into the 80s? I will have plenty of airation and filtration. P.M. me if you have worked with these fish.
