help my fish are not well, thay are clamping their fins and sitting in corners of the tank, and my comet has a slight anmmonia burn!

i have tested the water and my results are:
ammonia-2.5
PH-7.8
nitrite-0.0

are these results ok?
my fish were ok yesterday, but today i noticed my fantail clamping his fins and sitting in a corner, my comet is the same and has a slight ammonia burn that was not there yesterday, and one of my moors are clamping his fins.
could this be the water?

the rest of the fish are fine but i am not sure what the problem is and am worried they might die if i don't sort it out soon

---------------------------------------------------

now its gotton worse, i just don't know what to do?
i put some medicine (that lowers ammonia ) in the water but when i tested the water for ammonia it seemed to make it worse, 5 of the fish are fine, but 2 are not well and the third is in a very bad way.
i changed 50% of the water today but my fantail (pippin) has got bloody fins, has lost a few scales, gasping for air, he is still alive but is just hanging in the water and hardly moving.
my comet has got a slight amonia burn on his dorsal fin, and i saw another on his pelvic fin today, his tail fin has gotton red and bloody, and he is just sitting on the bottom!
he also can no longer swim properly, he twists around as if he has swim bladder (but i know he hasn't).
my other sick fish is not as bad, he is swimming around ok but somtimes clamps his fins and sits on the bottom, his tail fins are torn and jagged!

what should i do!!??

will my fantail survive until i sort out the problem???!!

i realy need help!!!!!!!

Hi,2.5 is a high reading for your ammonia. Is this a new tank for you,or has it been up a while? A cycled tank should always read zero for Ammonia and Nitrites,and for Nitrates,anything reading under 20 ppm's is good.Do you have a Nitrate test?
Ammonia is really deadly for fish.What medicine did you use to help it? After you changed out 50% water,did you take another ammonia reading?What were the results? If you're still reading a high ammonia reading,you'll definately need to do another big water change.Please post back with results.
By the way,I see you have quite a few fish listed,are these all in the same tank,and if so what size tank and filter are you using?If you look above ,there's a list of questions that we ask.If you can try and answer as many as you can,that will help us greatly on what to do with your fish.Post soon.

to late, the fantil has died and the moor is not looking good

before you say it, i know this tank is i little crowded, but the fish are small, the tank is 22 gallons. but i think the problem must have started when i bought the fish, the tank has been running for about 2 years but must have added to many fish at one time. when my shubunkin (toscar) died, i bought, 5 goldfish at one time, very stupid thing to do but i didn't think of it at the time. then my other shubunkin died from what could have been ammonia (not sure). but i have had the new fish (along with the old ones) for about 3-4 weeks without any problems.
how do i return the ammonia level to 0?
and will the other fish survive until then?

i don't have a nitrate test kit.
it is difficult do read the results of the ammonis, it is coloured yellowish at the moment but is very pale, but i guess it is about 1,0 shuld i keep doing water changes?

i have learn my lesson and am not going to croud my tank up by buy any more goldfish, and am planning (with my Dads permission) to buy a new tank, i have got a new job and am saving up for it.

If you have thrown your tank into a mini cycle by adding too many fish at once, you have to do large water changes- 50% maybe 2 times a day until your readings are at the very low end because any ammonia and nitrites are harmful to your fish. Test for ammonia and nitrites before the water changes. Check for nitrates now and see if you have any. If you can't buy one right away it is ok. It will be helpful to know whenyou are finishing up the cycle but if you had ammonia, then nitrites and they go away, you should have nitrates. Nitrates mean your cycle is working but with all the water changes you are going to dilute that as well anyway. Once your tank is cycled you want to test for nitrates to keep them below 20 with weekly water changes.

Do you understand how the cycle of ammonia, nitrites, and nitrates affects your fish?

Another thing you should know is your tank pH and the pH out of your faucet. It will help you know if there is another area that needs attention during this process.

To help your fish through the cycling process you can use aquarium salt at 1 teaspoon per gallon of water to give you a .1% solution. So if you have a 22 gal. and no gravel/ornaments/rocks etc. you could add 22 teaspoons of aquar. salt. Dissolve it in some of your newly changed tank water that has been dechlorinated and pour it in (stay away from your fish and filter when you add it). The salt will help the fish handle the ammonia/nitrites better.

You can use Prime as your water conditioner as well. It will help protect your fish from ammonia and nitrites. Use it at 5 times the strength (directions on the bottle) while the cycle is proceeding. Prime changes the ammonia to a safe form for the fish but most test kits still show that ammonia is present. As long as the fish are acting ok you know they are being protected by the Prime.

Feed sparingly during this time because unused food and poop means more ammonia.

Recap- test your tank water, do water changes (remember to add back in the salt/Prime you remove with the water) twice daily if necessary until you see ammonia appear, then nitrites as the ammonia is going down, and then nitrates appear as the nitrites go down. It can take 4-6 weeks and that is a lot of water changes! If you change 50% of the water you would have to add back in 11 teas. of salt with each water change.

sadly my comet has died, and i don't think my moor is going to make it. is there any way i can put him to sleep humanly.
the ammonia level is 0 and the other fish are ok but sam is just to weak. any replys would be greatly apperciated

How is the moor doing today, Mary-Ann? If he is still alive and kicking, then he might just make it.
Keep an eye on those ammonia/nitrite/nitrate readings, and do more frequent water changes. If it has to be, every other day. You still got 3 fish, right? 2 of them need more space to begin with, so you have to counterreact with the lack of space by doing much more water changes.

my moor is still alive but not doing very well, he is now swimming on his side but i tested the water and it looks fine.
i have 4 other fish and hope to buy a new tank

Sorry that he isn't doing well. Could you please post what the params of the tank are again so that we might help you.
