Why did my goldfish die so quickly?

Question

Yesterday, I changed my fish tank's water due to the fogginess of the tank. As soon as I put them back into the bowl, the youngest fish started swimming to the top as if gasping for air. The second fish died this afternoon when I got home from the mall. The second fish did not float to the top. Instead, it sank down to the bottom and passed away with it's mouth open. I hope that I did not suffocate my pets. I guess my real question here is why did my fish die so quickly in water that I just changed?

Answer 1

because of oxygen and gold fishes cannot live in a bowl it will suffocate them and them die

Answer 2

A goldfish should be in a minimum of a 20 gallon tank with 10 more gallons for each additional fish.  All water should be treated with a decholorinator before being added to the tank and the water should be at the same temperature as the old water.  Goldfish have very short lifespans in bowls.

Answer 3

first you didnt put settled water then it could have chlorine in it second no aerator bowl is too small when clean the tank use biggest basin possible with aerator.   then used settled water for 3 days.  Chorile is poison and poluted water easily destroy oxygen in the water fast.

Answer 4

becuase they are in a bowl, you didn't dechlorinate the water, and bowls cannot cycle.

Goldfish CANNOT live in a bowl

Answer 5

Sometimes, due to the immediate change of water, the fish doesnt have enough time to adapt to the water. Or, you might need a heater or a air device. When you switched the water, it was probably too cold or too warm. This happens with a lot of fish.

For example, a red cap can only survive in tropical waters.

Answer 6

The answer to this question is simple: you had your goldfish in a bowl.

Answer 7

When changing the water it is important that the water from the tank is the same temperature as the new water. This could be one reason why the fish "kicked the bucket".

For future reference, when changing the water take some of the dirty water out and put it in a baggy (similar to the type you probably got when you got the fish) then put the fish in that baggy and tie it up. After, fill a small bucket with the new, clean water and place the baggy in that. Let the fish sit there for some time and allow the water to match temperature (doesn't have to be perfect, but as close to it as possible). Clean the tank, do some other stuff around the house and then check the temperature of the baggy by touch. If it feels the same, put the new water in the tank, untie the baggy and drain most of the water (be careful not to lose a fish ;-)) and dump the remaining water and fish back into the tank.

If the tank is a little bigger, I suggest purchasing one of those sucker fishies to do the cleaning for you. Or if its a big tank with many fish a really good filter will help. In the bigger tanks a bubble machine will help too.

Also, if it was a goldfish you won at say a State or County fair I suggest feeding it once a week. This isn't proven, but it kept one of my goldfish alive for a long time!
