My fish are dying - please help !
Hi all,
I have a mature pond about 8 years old, 800 gallons, about 50 goldfish ranging from tiny tiddlers to about 5" long, plus one really big ghost koi about 18" long. I have all the usual filtration, waterfall and oxygenating plants, UV light, water is nice and clean and clear and always has been. I feed the fish about every couple of days - if they get too much they get frisky. Big problem - In the last week I've found 3 of the larger goldfish just floating dead in the water. They have no signs of any disease and look perfectly OK, just dead. This is very distressing as I'm spending every moment checking the pond and expecting all my little friends to die. I put some medifin in the pond a couple of days ago (I treat it twice a year normally - Spring and Autumn), but I've had another death since then. The only thing that's changed recently (don't know if it could possibly be the reason) - I recently netted the pond because we were visited by a heron, then I realised that the frogs and newts couldn't get in and out so I put a length of wood into the water from the side. the wood is sapele (sp?) and is definitely untreated, but I know some hardwoods have funny substances in them - do you think this might have poisoned the water ?? What shall I do ? Please get back to me soon - I'm desperate to save them. Thanks, Carole |

the key is "the larger" fish died. this is almost always a sign of
problems with enough oxygen. oxygen problems occur as water temps increase. they die in the early morning hours. at any time you see fish at the surface "piping". otherwise, it could be a disease attacking the gills. it could be toxins, so do take the board out of the water and only use plain pine in the water. you dont have any yew trees or bushes around do you? yew is extremely toxic, sometimes the berries drop into the water. the other think it might be is infection of egg bound female fish. you would need to do a necropsy and see if the egg sacks are yellow... any color but clear/white. http://weloveteaching.com/puregold/d...e/gf_anat.html Ingrid On Sat, 23 Jun 2007 11:24:08 +0100, "Carole" wrote: I have a mature pond about 8 years old, 800 gallons, about 50 goldfish ranging from tiny tiddlers to about 5" long, plus one really big ghost koi about 18" long.

Well, I'm surprised you bothered replying to a call for help - your manner
is hostileand arrogant - not what I would call helpful. You may be an 'expert' on ponds, but clearly that's about all you've got going for you. American I suspect ? Once you've finished your ego-trip, and if you care to continue this dialogue (which I doubt), I can tell you the following : Here in the UK the term 'tiddler' is extremely common - it refers to anything very small (ie 'tiddly'). Not a big issue really is it ? I have pond test kits and use them regularly - recent tests (a couple of weeks ago gave the following results : - Ammonia less than 0.1 - no problem - Nitrate zero - no problem - PH 8.5 - acceptable. The 'usual' filtering system comprises two large drums containing filter brushes and 'foam' pads - these are cleaned 2-3 times a year. I assume you know what a UV light is ? There is a drain/filter at the bottom of the pond which takes out the water and feeds it through the filter system and back up into a small top pond, over a small waterfall, and back into the main pond. Pretty usual I would say. Many of your other questions I have already provided information for, such as feeding, timescale for the deaths, condition at death. I top up the pond every few weeks, as and when needed due to evaporation, from a tap and use a water conditioner at the same time. Nothing has been added to the pond for as long as I can remember apart from the wood I mentioned (which obviously I immediately removed - I'd be stupid otherwise wouldn't I ? and I'm not) Further (courteous and constructive) assistance would be appreciated, but don't bother if it's too much trouble for you.

Thanks for this Ingrid,
I'd be surprised if it was an oxygen problem - temperatures here in the UK are low for June - and we've had torrential rain for most of the month. I have a waterfall, and loads of oxygenating plants to keep the oxygen level up. But I agree, it's strange that it's the bigger fish that have died (I would guess they're about 5 years old). I assume that is there was a 'poison' problem the little ones would have gone first. Now I think of it - I found all the bodies next to the piece of wood, but assumed they had been washed there because the input flow is at the opposite end. Maybe the larger fish had been nibbling at the wood and it had something in it which killed them, rather than my initial thought that maybe the wood had leached something out. Well I've removed the wood now, so I can only wait and see.

Hi Carole,
I have all the usual filtration, waterfall and oxygenating plants, UV light No air stones? Plants will not be enough. I feed the fish about every couple of days - if they get too much they get frisky. That Ghost will be eating the little ones if you don't feed it more often! I had 4 Ghosties of that size once ... When they were hungry they'd try and eat the paving slabs around the edge of the pond! Big problem - In the last week I've found 3 of the larger goldfish just floating dead in the water. Are the other fish gasping at the surface? I'd be running a KA25 with that level of stock. I put some medifin in the pond a couple of days ago (I treat it twice a year normally - Spring and Autumn), Reasonable enough, but if the fish don't look distressed or diseased, I wouldn't bother. I used to treat with Medifin like you are, but I haven't bothered for a few years as it simply wasn't necessary. The only thing that's changed recently (don't know if it could possibly be the reason) - I recently netted the pond because we were visited by a heron The old "fishing line tied around canes" trick works best! hardwoods have funny substances in them - do you think this might have poisoned the water ?? I doubt it. Given the amount of crap that ends up in my pond (leaves, branches, mice, hedgehogs, dead frogs ...) and that I've not had problems would suggest not. What shall I do ? Buy an air pump, some tubing, a few airstones, and see what happens. Certainly won't cause any harm. Also, talk to your local aquatic centre people and ask if they've had similar problems reported from customers. Cheers, Al. |

You're stocked like a dealer. Goldfish and koi are both big eaters and pass a lot of feces - unless you cruelly starve them. Mine are fed twice a day and are indeed frisky as healthy fish should be. Then you have a large koi also! I hope you're doing at least bi-weekly good size partial water changes on your small pond, using dechlorinating product. As Roy said, it's not good to medicate if you have no idea what you're medicating them for. It just adds more pollution to the water than the fish already do. -- RM....

rain dissolves a lot of CO2, which becomes a mild acid. it is usually
pretty warm and there isnt much O2 in the rain water. oxygenating plants give oxygen during the day and use it up at night. big fish going first is a problem with getting enough oxygen, either in the water, or attack on the gills by toxic water or parasites.
