This reminds me of when my tank experienced a mass death approx 12 months ago. Fish dying for seemingly no reason, no symptoms, nothing wrong just dying. Then I realised i was poisoning the tank with flea poison which had come from a dog toy which was accidentally sitting in the filter. Luckily I got it sorted but eventually all fish exposed to that tank over that period died of weird things within a few weeks of each other.
