hi can anyone tell me why my goldfish is near the top of pond, not eating or moving much, just mouth opening and shutting ?
Sounds like it - water needs aerating.
Either lack of oxygen or build up of toxins do you have a pump and filter system?
We ve got pump, filter, oxygenating planting, 4 small fish, good sized pond for them, one is bigger than the other 3, I thought they were flirting and blowing kisses at me! I spoke to our local fishy place, because they were chasing each other, he told me why!!!!!
Run a splashy hose into the pond to aerate it. If the pond is small with no water movement then it can easily overheat in this warm weather and lose the oxygen out of the water. Make sure you have oxygenating plants in it.
I was told you must leave water for several hours to de-clorinate before adding to pond if you have fish.
If you pour some "chlorinated" water in, but not much it's not a problem. If the chlorinated water is cold it also helps lower the temperature a bit. Make sure there is some shade on very hot days. If the pond is large and deep it does not matter much... if the pond is small a large potted plant to the south in the afternooons might be enough. Alternately ***if the pond is big enough for the fish to hide in a safe place***, you can churn the water vigourously with a bamboo pole or something similar for five minutes. In my "no mechanics" pond I do that a few times in spring when the water is going green. Excellent exercise too.
Thank you everyone for your comments, we have a solar aerator and also plants, hopefully it will recover we lost one fish a couple of days ago
When the weather is sunny and hot you really need to react quickly if things are so bad the fish are dying. If the local water is not good enough to put straight in, buy a small fountain and pump and run it 24 hours a day, making the water shoot up as high as possible and come down as droplets. It may look a bit naff but the fish won't object if it saves their lives so neither should you!
Prolonged warm humid weather seems often the culprit. With just a solar aerator you're getting barely any oxygen into the pond and I would guess that the warm weather has just tipped the balance in favour of some bacterial flourish and given you them problems you've had. The aerator may help move the water about a little bit but you really need to get the water moving properly. Ideally a waterfall and/or fountain and you'll see a big improvement.
I change around 10% of the pond water every 10 days or so using straight tap water.If you want to do a big change with tap water, you can buy something called Prime which de-chlorinates the water 1/2 capful treats 50galls.Hope it turns out well
Because when I change 50% water (60galls) in my tropical fish tank, in my view It's better to spend around 15p to remove the chlorine rather than wait for nature and risk dead fish.
Seachem Prime has been around for 20/30 yrs and has vast numbers of happy users
Each to their own - but I'd be interested to know under what circumstances it didn't work for you
