Okay, first of all, you have to read the whole thing before answering....

My platy had some ich, so I cranked the temp up to kill it, (which I've done before w/ close monitoring, (temp was at 90F) and my fish were perfectly fine, and the ich was gone very soon.) and then left the tank, because I had company over.

I came back a couple hours later, and the tank was over 100F!!!!! :blink: :blink: :blink: :blink: :sick: :sick: :sick:
I turned off the aquarium light, turned down the heater, put an airstone in, put some icecubes in, and opened the lid and pointed a fan towards the tank. I know I shouldn't cool the tank down too much at once, because that will stress out the fish like crazy, but they are literally dying of heat exhaustion! :crazy:

A couple guppies already died, and the rest of the fish are floating around and gasping at the surface, and I'm trying to aerate the tank the best I can.

Like I said before, I don't want to cool the tank down too fast, because than the fish will die of stress, (like they're already not stressed enough! :( ) but I also don't want to cool it down too slow, because than the fish will die from the heat!

In half an hour or so, the temp already went down 5 degrees F, which I know is dangerously fast.

This was all a stupid mistake. My heater doesn't have the temps marked down, and I thought that was how much I cranked it up last time. I know I should've been checking on the temp, but I was pretty busy.

Also, I don't need criticism, because I've already given myself enough of that, trust me. :-(

So what should I do? Cool it down quickly and risk death from stress? Or cool it down slowly and risk heat related death? :(
 
My policy has always been that you can take cold(er) water to the fish, but you cannot take a fish to cold(er) water.... I would simply have done a 50% water change.....

That's what I was thinking.....
I probably should of done a few things differently, but it's too late now... :sad:
 
In cases like this, you can actually aerate the tank by simply dipping water out with a cup and pouring it back in. The surface disturbance is what aerates the water, not the bubbles from the air stone. I agree that you want to cool the water and not just plop the fish into cooler water. I wouldn't think 5 to 10 degrees per hour is that bad and you could probably go more than that. Some postings in the past have stated that fish take several days to acclimate to a new temperature so it's not likely they are used to the high temp, simply gasping for lack of oxygen. I would think it likely the deaths are from lack of oxygen (or high carbon dioxide) as opposed to the temperature itself.
 
Sorry for your loss. You did the best you could. Hopefully, you will not make that mistake again next time.
 
Thank you very much. Now that I think about it, that makes sense....
I was just so panicked when I wrote this... I'm going to check on the fish again now... and remove the dead ones.... :(
 
Consider ur self lucky already, I had experiance full tank of 5 gold fish cook from defected heater over night. Oh boy the next day I find gold fish soup in that tank and temparature is 60c. And boy it stinks too. And the body of the fish looks like :sick: .
 
Oh man! :sick: I feel for you! :(
I am considering myself luck... I'm very happy that only two fish died. :)
 
I heard that as well, but my tank wasn't that well aerated until I put the airline tubing in. (Which was when the tank was already at 100F) Thanks. :good:
