dying fish-need help please
I am in need of some advice and hope you could help.
I am having a fish die-off. They are goldfish and the pond is about 6 years old. I have never had anything like this happen before. There aren't any appearant signs of infection on the fish. The only symptoms that I see are listlessness at the end of their life. They lose their appetite. There haven't been any plant or fish additions to the pond. The only connection that I have seen is this-toads come to mate in my pond as in previous years. This year, I found a dead toad floating in my pond, which I took out. That was about 3-4 weeks ago. Later, all of the tadpoles died off. There currently are more and they seem to be doing all right. In the past week, I have had 1-3 fish die every day. Is it possible that the toad carried a virus that infected the fish? I have done a water change this past weekend of about 30%. I medicated it twice with a combination of formalin and malachite green. The pond is about 3,000 gallons and has an external filtering system. I am at a loss. None of the diseases that I have seen described match this. I am hoping someone will have some suggestions. Thanks, Ray |

What are your water parameters (ammonia, nitrate, ph, etc)?

Sorry to hear about your fish: it's always distressing to watch them die and
not know why. Disease is always a possibility, but the first thing that you need to check is your water parameters: what are they? At this point, I would be most concerned about ammonia and pH. Where are you located? What is the water temp? These things need to be known before anyone can give a "guesstimate". Lee "ray hucek" wrote in message ...

But my gut reaction says it could be an imbalance in water quality parameters, specifically Ph, ammonia, low dissolved oxygen, some kind of chemical poisoning, or a bacterial infection. |

Thanks for the reply. I had about 75-80 fish ranging from fry to 6 inches,
but mostly 3-4 ins. I tested the water and forgot to give the findings in my original posting. Sorry-- PH -7.4-7.6 Ammon-- less than 1 PPM. Nitrite-- .25 water temp- 80 degrees The toad and tadpoles were dead before treating the pond. Any help would be appreciated. Ray "Ka30P" wrote in message ... Hi Ray, that's too bad :-( A few questions before the experts arrive, - How many fish in the pond and appx. how big are they? Water test results, exact numbers? malachite green This can be fatal to amphibians. Did they die before or after you treated? Hope someone has an answer for you.

Jay,
Thanks for the reply. I will try to find the Copper or Dylox. And I will add in more aeration. I live in Oklahoma and we did have a short spring.

George,
Thanks for your thoughts. I tested the water and forgot to give the findings in my original posting. Sorry-- PH -7.4-7.6 Ammon-- less than 1 PPM. Nitrite-- .25 water temp- 80 degrees All of the above seem to be descent. PH is a little high, but seem to be acceptable. What do you think? Chemical Poisoning-- it would have to be airborne because I don't do any fertilizing or pesticides in my back yard. And there is no risk of runoff into the pond. I thought of that when I did the water change. I was hopeful that doing the water change would have diluted any poisoning taking place. It didn't seem to work as I lost 3 fish today. I am going to increase aeration to try to deal with oxygen. Any ideas about bacterial infections and how to treat them? There isn't any outward signs on the fish. Any help would be appreciated.

Hi, I am sorry for your loss. I had a mass tadpole death last year but it was my fault. This year, so far, so good. It really sounds like poisoning to me. Good luck in the future....

your water has gone toxic, most likely from the spawning of toads. DO NOT TREAT WITH
MEDICINES. this will just make it more toxic. water changes!!!!!! get those toads and toadpoles and eggs out of there. If you have to drain the pond, move the fish to a kiddie pool and clean all those toadpoles outta there. if you dont have hellatious aeration in this pond get an air blower from aquatic ecosystems and 4 of their foot long sintered glass air stones to put oxygen into this pond. between the ammonia and the temp of the water the fish are smothering.

My test kit says that levels of 0.25 mg/litre of ammonia can be lethal. I
don't have the conversion to PPM, maybe Ingrid or someone else can chime in. My test kit also says that "As far as possible the nitrite concentration should not exceed 0.20 mg/litre. At a level of 0.5 mg the fish will be adversely affected." Both ammonia and nitrite in high levels prevent fish from obtaining and carrying oxygen. Also: This is a long shot, but has your community switched from chlorine to chloramine in tap water? The latter takes way longer to dissipate (in fact I can't find anything that says it ever dissipates) and I'm wondering if you use a dechlorinator? If not, you might go get a jug of amquel. It will have the side benefit of reducing your ammonia level. Would you consider your filters effective? Poor filtering could lead to higher nitrite levels. Sorry, don't know much about parasites, but many others on this list can pipe in on the subject. Joe On 5/18/04 2:13 PM, "ray hucek" wrote: Joe, Thanks for the reply.
