Goldfish Death Due To Fin Rot

[emilythestrange]

I came in yesterday and saw the first signs of fin rot, after i went work yesterday, before i went nothing was wrong, afterwards when i came home, he had streaked fins looking ripped and a huge red mark on the stump on his tail. I went to pets at home that night and brought Fugus and fin rot treatment, measured out the right amount,

However this morning i woke at 7 30 am and i thought he was still alive but the filter was swaying him, he was dead..
Im not so sure about what to do with the tank and how to protect my other 4 fish, I took a water test and the pet shop owner told me my ammonia and nitrate levels were very high

A few questions:
1) How large is your tank
2) Was it cycled before you put fish in?
3) Are the remaining 4 fish goldfish or something different?

The first thing you need to do is start doing large water changes to reduce the ammonia and nitrite levels. It sounds like either your tank wasn't cycled, or the biological filter has been overwhelmed/crashed. If you don't have a test kit you'll want to buy one now because you need to keep the ammonia and nitrite levels below 0.25 ppm, and do a partial water change every time it creeps over that level.

Fin rot is most commonly associated with poor water quality, and clean water is the best way to prevent it from occurring in the first place.

*edit*
I checked your profile after I made this post and noticed that your tank is only 27 L, which is much too small to maintain even one goldfish into adulthood. Goldfish are very heavy waste producers, and most grow rather large, which means that not only do they require space but also a larger volume of water to help diffuse all of the nitrous waste.

Yes there are now 3 fancy goldfish and 1 telescope
No the tank wasnt fully cycled before i put the fish in, they are only small at the moment, I did a water chang eafter i took the dead goldfish away,.
Was that the best thing to do?
The fin rot produced very fast with in 5 hours that day, i tried to treat him but it obviousely was too late

sounds like septiceamia which is blood poisoning caused by high ammonia. Its a bcterial infection which then weakens the fish allowing other diseases to take hold.
I agree with the posters that your tank isnt suitable. for 3 fantails youre looking at a minimum of around 30 to 40 gallons and a big capacity filter.
