So my house has been HOT lately. Stupid Wisconsin, -20 in the winter, 90+ in the summer. *grumble grumble*
One of my CT's died yesterday, and I'm perplexed as to why. I have always done water changes (it's a 5gal) 2x a week with a thorough gravel vacuuming. I always carefully monitor my water specs. He was happy and healthy until two days ago. He was totally clamped up, lost a lot of color, so I put him in the hospital tank and this morning he was dead.
The only thing I can think of, is that the tank temperature was too high. My tank thermometer goes up to 86 degrees, and it is higher than that. For the time being, I keep the light off as much as I can and the heater is set much lower, but it is still just HOT in my house. I don't have central air.
Could this have caused Admiral Fishstick's untimely death? What is the temperature threshold for bettas?
