Losing Fish Rapidly Need Help Please!

[chamberpot]

C'mon mate post your stats.
These guys are bending over backwards to help you, but without all the facts they're struggling. For you to have so many, rapid deaths in your tank, your fish must either have one of the diseases that wilder is suggesting, or they have been poisoned by something in your water.
They need to eliminate water contamination, so you need to give them your stats. It can only help.

Best of luck, Don.

ammonia=0
no2=0
no3=5

AHHHHHHHHHHHHH!!!!
How has this happened?

ph= 6.4
ammonia= 4-5!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

tanks cycling for some reason, explains all the deaths.

i'm sorry to say but your previous reticence to post actual stats leads me to believe that you weren't previously testing the water.

do a massive water change immediately, 75% of the water. you'll then need to do a minimum of 10% changes every day until ammonia and nitrite both hit 0. If you have another healthy and stable tank then get some media from that and put it in the filter which should help a lot.

if you see from my previous post i tested water on 19th which were fine and now today whcih is only 4 days difference!!!!
usually i test it once a week if there is nothing wrong with it. so what is the problem i dont see what you mean!!!

 

[chamberpot]

That was 4 days ago though. When did your fish start dying?
Your fish are swimming in acid is what I think they mean.

it looks like the tank has stopped cycling for what ever reason which is why you are now seeing no nitrate or nitrite readings and a high level of ammonia, which at 4 or 5 will cause severe damage or death to your fish.

i personally would have been testing the levels every day at least whilst you had a problem with the tank or the fish to ensure you caught any spikes in levels before they caused any more damage. unfortunately you will now have to start the cycle again and id start by doing a large 50% water change asap, and then another one later to try and get the ammonia down to a safe level below 0.25 and then start testing the levels twice a day and do water changes as and when they are required

As I told you in my post a day or two ago if you've an unexplained death (or several) then the single most important thing to do is keep on top of water quality. If you're not even testing then how can you know it's good? Test every single day if you're having problems, ammonia is unlikely to have jumped to 4 overnight unless something's happened like the filter's been turned off, this will be something that's built up gradually, testing everyday would have meant you'd have spotted it sooner.

 

[rocknurworld2006]

they started dying 6 days ago o i done a water test 2 days after they started dying and everything was fine

anyway ive decided to strip down tank and start again, cause it wasnt ammonia that started fish deaths at least!!!
so there could be another underlying problem!!

but thanks for all your help much appreciated!!!!!

 

[WILDER]

Would explain the slightly inflamed gills.
Can only help if you give us the full information.
You said three tanks to me then told you had six on another thread.

 

[rocknurworld2006]

i did give full information!!!!

and i did not state anywhere where i had 3 tanks

 

[WILDER]

You did you removed it.

 

[rocknurworld2006]

removed what?

Another thing that your fish could have been dying from is columnaris. I just lost 2 fish to it and they had the same symptoms you described on the fish you had that died. I am hoping I have mine under control now but we will see. They could have gotten that from stress or water quality going poor. If it was columnaris you will need to either treat your tank or break it down and bleach it and then rinse, rinse, rinse and heavily decholorinate the tank and every thing that was in it as well as the filter and heater. You may want to google columnaris and read the symptoms and look at some pics and see if it is a possiblity.
