Water temp varies, I originally found them in geothermal area so the water was obviously kept quite warm, put them into a pond where it would have been cooler, however the warm weather will have increased the temp in there substantially - small pond.
Pretty sure the shops were selling goldens.
So I should leave them in there to morph over summer?
One of them only has 1 eye, a birth defect I think, its kind of cool actually.
