Yesterday I came in to one of my fish floating in a 60 gallon tank that it had to itself. I'm still trying to understand what happened to the fish because it seemed healthy up until this point? If this helps I live in a really old 2 story rent house on the first and second floor. this particular tank was on the second floor and I think the tank just overheated and I cooked my fish on accident. My girlfriend and I usually leave the A/C on in the house when we are comming in and out but we were out of town today and turned it off. We have done this before and no fish in the house have died if anything I just figured it gave my heaters a slight break, however when we left today it just so happens that the tank was in a room my girlfriend pulled the blinds back in that morning to do her makeup and left them open. She's arguing me saying the fish was just old (which it was I think?) or it died of some other cause (my fault) but I think the fish was cooked and I need some help determining this! the water was a good 85 degrees when I came home and the room felt about 95 it was hot as hell in the appartment I'm not sure how hot the tank was durring the middle of the day but it had already been dark for a couple hours when I got home. What do you guys think? Did the fish die to some odd reason or did it get cooked durring the heat of the day? Also I'm moving the tank to my bedroom after this. Just let me know and I'll show her the input, has this happened to any of you?
