PlEaSe HELP MY FISH ARE DYING!!!!

I had 13 lovely gold fish 3 weeks ago and now I am left with 5. They all started off lying at the bottom off the tank. Then very quickly just floating around gasping for air. (gills pulsing rapidly). I put them in isolation as I dont want them to spread the infection around.
I did a 50% water change as ammonia was up a bit but they still look sick.
PH is good and ammonia fine now.
what can it be?

One of my fish that died lost his tail completely and then died. but none of the others did this.

Naomi,

How big is your tank? Did you introduce all the fish at the same time? IF you
did
your cycle would have spiraled out of control and ammonia would've shot through
the
roof which would definitely have been a cause of death!

My first guess is a cycling problem. Are you checking nitrites and nitrates
as well? I assume you are adding a water conditioner to remove chlorine.
Do you have an airstone(s)? None of these would explain the tail Of
course, in the long run you would need a huge tank for 13 GF. In the short
run 2 1/2 galllons per inch of fish seems to be a good guideline. HTH

EMERGENCY
1. check the water parameters: pH, ammonia, nitrite, nitrates
2. do the fish physical
3. change some or all of the water
4. from the water parameters and physical decide on a course of action
5. if there is nothing specific, do the tub to tub method
