Fish are dead.. thanks for the help anyway guys. nvr buying from wal-mart again.

that's too bad . . . was this a new tank or anything? it would be interesting to know exactly what happened

that was a really weird answer, "nitrogen bubbles", how did you come to that conclusion?
 
lol nitrogen bubbles did they ascend to the surface of the tank to fast ? you must have a preety damn deep tank


my money is on ammonia or nitrite poisoning.

Hanson, If you want to avoid making the same mistake twice, you must identify that mistake.

I doubt there is anyone on this forum, myself included, who hasn't made an error that cost a fish it's life.

Read the other posts on this thread, Identify your mistake(s), accept responsibility and learn from this experience.

With rare exception, everybody on MFK just wants to help. :)
 
Death by gas emboli is possible if one does a rapid and sufficiently large water change with cold water (which holds more dissolved gases). As the water is heated, the gases come out of solution.

There are more likely n00b mistakes though. When people tell you to acclimate fish properly or to do water changes gradually, they ain't BSing you.
 
nitrogen bubbles, maybe microbubbles from water change? I did that one time, hooked the hose into the tank, turned on the faucet, and the water turned white from the microbubbles.. Next day 4 dead fish and one laying on hte bottom gulping. I held that one upright into the power-head stream and he survived.
 
There are so many ways to kill your fish via a water change. That may be one of them. Usually, if you're at risk of gas emboli, there will be bubbles on every surface in the tank. Many years ago, I refilled my tanks directly from my RO filter and wondered why they always seemed to breathe hard during and after the refill. It was the cold water being heated in the tank making the dissolved gases come out of solution and/or the chlorine/ammonia getting through my RO (which is why I now have a 13 stage RO filter).

I once attached an oxygen concentrator to an airstone. It was quite helpful since it outputs 85-90% oxygen which is a lot higher than normal atmospheric oxygen concentrations.

Did you do a water change and forget the dechlor? Usually when thing go bad in an hour, user error is the most likely cause.

"nvr buying from wal-mart again."

I think it should be the other way around:

Walmart should never sell fish to you again.


I have to agree here. Fish don't die that fast unless the owner screwed up, and this stinks of lack of experience X uncycled tank X chlorinated water = dead fish.

How does one jump to a conclusion like nitrogen bubbles?
