I think it's excessive ammonia - got some stuff coming today to hopefully sort it - but now I'm checking periodically to make sure no more fish have died.

I don't want the fish, but don't really want them to die...

Sorry to hear this Mr LM maybe this link below could be of help to you. I noticed that it states weather change (a heat wave in the weather since warmer water cannot hold as much oxygen, a surge in temperature can have a detrimental effect on dissolved oxygen) anyway whatever it is I hope you get it sorted.
