My goldfish pond has had happy fish in it for 4 years now and suddenly I've
had 2 of them die within a week. No signs of disease or trauma...I live in
south TX where the temp has averaged 100 lately, I'm wondering if the water
is too hot for the poor guys. I know they do best in cooler waters. My
plants are fine, lilies blooming, frogs living happily in the water too.
Any ideas?
