All of my guppies died, everyone else is fine?
I have a 15 gallon that I just have a few white cloud minnows in and they've been there for a couple years, I just took in a few unwanted guppies and within 1 week they all died. The white clouds are as fine as ever. I tested the water and everything came out fine, water temp is 78.
I'm a little baffled as to what could have killed them, I've kept plenty of guppies in the past and have found them tough as nails. There were no signs of parasites or other afflictions or nipping from the minnows, I just woke up one day and one had clamped fins and was wobbling, in the coming days the same thing happened to the other guppies.
