Your tank had soft/acidic fish and hard/basic fish, which isn't a good idea, but that seems to be a problem aside from what caused the deaths. Your tank was also overstocked in both space and filtration, not even counting the juveniles.So that's a problem. If we figure this out and you start up your tank again, you should get an API Master Kit so you can keep an eye on the exact values. I'm sorry to hear about your fish!
Thanks Mina, Last water change was Sunday morning. That's what made me go get a thermometer in the first place. My hands felt cold, so I thought I would check the temp. I don't use any water conditioner. I just use filtered water.
No, I don't know the actual numbers. Sorry. I know that would help. I am aware the tank was getting too full, I was getting a 55 gallon for christmas. Hopefully that isn't the ultimate cause of this.
