67* not 86 haha only 67 hatched.
We had been going through a severe heat wave and temperatures in the tank sat at almost 90F for 2-3 weeks even without a heater, unfortunately some of the fry weren't strong enough to deal with the temperatures for so long. But there wasn't anything I could do to bring the temperatures down. Even had the air conditioner running and it wasn't enough.
Outside temperatures got up to 115F
