If water tests are good and dead fish appear good, and you've got aeration going.....I'm a little stumped, especially as multiple fish have all died. It's possible it's a parasite, although as that progresses the fish usually develop secondary ulcers.

There are some microscopic parasites, but without a microscope you'd never know.

This has me totally puzzled. How large were the mosquito fish you added? Never heard of feeding goldfish other species. Are there any mosquito fish still in the pond? I'm thinking they may not have been eaten but were sick and died and that lead to your fish loss.

Hi, sorry to hear your fish aren't doing well. Im relatively new here, so I may be missing some info if you've posted it elsewhere. Could you tell me - how many fish/what type, no. of gallons, what kind of filtration/aeration ?

Is the water as white and cloudy as it looks in the pics? Have you looked at pics of ich (aka white spot disease) - do your fish look like that? How do the gills look - nice and pink (good) or puffy and red(bad)?

Even if the fish have a specific disease like ich or gill flukes (problem I was having for a while), factors like poor water quality and over crowding would have be addressed along with doing the chemical treatement - those things can weaken a fish's immune system and make it more susceptible to disease. You could have several things going on at once. I would not get anymore fish until you get this sorted out.

BTw, there are things like dissolved organic compounds that can build up and are harmful to fish, and which wont show up in a water test. Have you done any water changes? You can in fact do pretty substantial water changes over a period of several days and it wont harm your beneficial bacteria since these live mostly in your filter media, sides of pond, tubing etc. (Of course any water added would have to be treated with a good dechlor like Prime or well water free of chlorine/chloramine.)

Anyway it would be helpful to have more info so we can get a better idea of what's going on. Otherwise its just guessing. Thanks, Catja in WI

The second picture in your first post......that fish looks like it could have ice or some type of fungus on it. I can't be sure as the picture is blurry. Did that fish have white spots? You mentioned other fish that died looked normal.

OK: I have decided to start all over.There are only 5 fish left that seem to be pretty active so i will put them in a 10 Gal fish tank for about 5 weeks while the new pond gets regulated.If the 5 fish survive i will add them back into the new pond water. I have three gold fish and two shubunkins left. Since i have no idea why they died i think i am out of options. Any better ideas would be very appreciated. Thanks

I think since there is no obvious reason then starting over may be the best option. You say you have 5 fish left. What happened to the mosquito fish?

I only found 1 mosquito fish dead at the bottom of the pond. Should i hose down all of the rocks that contain dead algae on it.
Are there any remedies to add to the fish tank to treat Ich? BTW: That mosquito fish was partially eaten.
Thanks

There are treatments available for ick. Check pet food stores. Hosing down the entire pond isn't a bad idea but that's just my opinion. Maybe someone else will have some ideas. I have never completely drained my ponds .

Wife thinks i should to see if the remaining fish also die. Or maybe i should just give them a Porcelain funeral.

No fins? Oh wait... I see perhaps they are clamped firmly to the body.... but still not the fins of a healthy fish. Tail is a bit ragged - looks like some serious fin rot? (Sarassas generally have longer, more substantial fins/tail) White cloudy water can be a sign of a bacterial bloom... and/or dissolved organic stuff in the water (fish poop, decaying plants, etc). So sorry , I know how frustrating/heartbreaking this kind of thing can be.

It looks like a parasitic “ulcer”.. from what I can see in the images. I used “melafix” in my own pond (about 800 gallon pond) and it cured and stopped any others from dying.

You can either “quarantine” the sick ones and treat them or you can dose the entire pond (that can get expensive) if you can’t catch the ones who seem sick..

The fish doesn't look healthy to me. Is the red streaking in the tail fin the way it normally appears? The pinkish tint to the other fins leads me to believe it died from a secondary bacterial infection. This generally starts with poor water conditions and the fishes overall health suffers, allowing parasites (always in the water) , the opportunity to enter the fish through reduced slime coat etc.

I also agree with @addy1 that the fish appears very thin. I'm still stumped as your water parameters are good. If it were my pond, I'd probably remove the remaining fish to a smaller tank and treat with a broad spectrum medication, while providing good aeration. Without a microscope you can't know exactly what to treat for.

Really sorry this is happening :(

I don't know if i removed all of the sick fish. So since the pond is empty now what if there are dead fish trapped behind the many rocks is it still possible for them to poison the pond?
