why are the fish in my pond dying?

Answer 1

I don't know, we need more info.
How big / deep is your pond?
Is it filtered / heated - if so, how?
What is your cleaning schedule?
What kind of fish do you have?
Do they apear to have a disease, or are they healthy one day and dead the next?
Have they all died at once or have they been dying off over a week or a month?
What are your ammonia, nitrite, nitrate, pH, GH levels?
How cold is your tank - is it frozen?
Is it possible something contaminated the water?

Answer 2

Perhaps you just don't have any idea how to care for them. If we knew certain things about them, we could give a more reliable answer. If you cannot answer any of these questions, then your fish are definitely dying of ignorance, and you should not replace them. If you can answer any of these questions, then add some additional details, or ask the question again with some specifics.

About how many fish, what kind, and what size are they?

About how much water does your pond contain?

Is there a filter? how large?

what is the temperature in the pond?

How long have you had it?

Did you treat the water with any chemicals before you added it?

Was it tap water or well water?

Have you changed the water or cleaned the pond at all since then?

Have you been testing for ammonia, nitrite, nitrate, pH, or anything?

Answer 3

You need to be more specific about your question. There are many reasons for fish to die in a pond. You should check out your local library for books on ponds or pond fish. You can always check in at your local pet shop where you purchased your fish. I don't have any information about your pond. Like where do you live. If it is the north east it is cold if your pond isn't more that 4 feet deep at one end with an area big enough to hold all your fish they maybe dieing of ex poser. Do you have a fountain or running water? The may be dieing because there isn't enough air in the water. How big is your bond? Is it at least 15 feet long and 8 feet wide with an area large enough to hold all the fish that is at least 4 feet deep? I really can't help you unless you give me more information...Check your local pet shop or the local library...Good luck...

Answer 4

I have two ponds. and my smaller pond we used to feed the fish every day. and they were dying. then we stopped feeding them and they ate algae off of the pond and survived and grew fast. We still feed our fish ocasionally. We give them goldfish pellets and worms, u can get the goldfish pellets from the petstores and worms from gas stations,petstores, and your yard. The fish might be getting eaten, weve had raccoons eat ours. or they might be picking on eachother. The fish might have a disease too.

Answer 5

you need to give us much more info so that we can answer you question
do you have any leaves or debris in your pond? this is deadly to fish, get the leaves out of the pond and do a good water change

Answer 6

If it's freezing...it could be a build-up of methane gas. We have a pond and we've lost one fish so far ;( But you can buy a de icer for like 50 bucks.
http://www.macarthurwatergardens.com has them...but there are plenty of places you can shop for one.

Answer 7

You could check if your pond is clean. Also, the temp. may be too hot or cold for them. If this doesn't resolve it, check with the owner that sold the fish or check with the local pet store.

Answer 8

most ponds are too shallow and fish will die in them in the winter months if your pond is 3 ft or deeper then you might want to start cleaning it atleast every year

Answer 9

try putting tennis balls in the pond then when it freezes over take the balls out so the fish can get oxygen

Answer 10

you may not have the pump working properly or there may be a lack of oxygen in the pod try and get yourself a good pump or may be some pod plants but if they are dying you may want to change everything in the pod to get rid of any bacteria the dead fish may produce.
