Water quality would be my guess. Lack of O2, big fish die first. The only
way to know would be to have the water tested..... and depending how long
ago this happened, the cause may have dissipated by this time. ~ jan

Sorry ,when I said the fish were in since October I hope no one read it as
the "dead" fish were there since then .Those were only in 1 day passed on
.Thanks for all your help .Greatly appreciated.

I didn't read it like that, most people would remove dead fish. :-) What I
was saying was the cause could be gone due to ammonia/nitrite breaking
down. If you got a water sample within 3 days in cold weather that would
tell one a lot. Regardless, the water should be check, as it could have
been pH crash, which won't clear up on its own. ~ jan
