Chagoi Had Popeye

[bigred]

Chagoi had pop eye and found him this afternoon floating. My pond is 90 degree with this wonderful heat wave in the valley. Friday=109, Saturday=112, Sunday=111, Monday=109, Today=107. All the other fish are fine. Could this cause the problem with the Chagoi?

Do you have any pictures of problem?

[bigred]

Nope, his eyes were back in his head when I pulled it out today. My mosquito fish were eating on him.

Pop eye is usually a sign of a serious systemic infection. Especially caused by Trichodina. With it usually comes swelling of the body starting behind the gills and then the rest of the body. If all your other fish are "fine" I would keep a close eye on them for any signs of being lethargic, reddening of the fins, hanging head down. You should stop feeding and do a 20-25% water change and keep close watch for any further development with the others.

All my other koi are doing fine. I'm only going to feed them at 5:30 AM when I go to work. The water SHOULD be cooler. I did a 20% water change today to also help cool things down a bit. I'm thinking of doing a 10-20% water change every three days to help cool the water. Also I'm buying some sunshade covers for it tomorrow.

How do I treat for this if it pops up again? No pun intended.

Another thing, I just went threw a Costia problem and PP the pond 3 times and had the fish in QT for 1.5 weeks and treated them with quick cure 2 dosages. I don't see how anything bad could make it. My thinking is it just boiled him with 90.3 degree water. I noticed he lost his Gin Rin the day before.

90F is going to be very hard on koi. Oxygen levels are marginal. The larger ones will have the worst time of it, and having gone through a recent parasite infection/PP treatment the gills would be a bit compromised in the best of times.

This is a good reminder that it is best for koi to have shade available, particularly in hot weather.

Pop eye normally caused by either bacteria attack on the eye or tremenduos stress on the koi. Since you have do all the parasite treatment, the only problem now is probably your pond have a high level of bacteria (aeromanos) If the koi have along with pop eye some fin rot, then that is aeromanos. A 100 % water change will solve the problem. Anything that can help bacteria grows need to be eliminated (plant, frogs, leftover food, ect..). Temperature at 90 is not something you should worry about if your pond is more than 3ft deep, we have 98, 100 for the last 4 week now, a shade definitely help a lot.

Steve,

While most of the popeye cases can be traced back to the usual suspects for dropsy, i.e., bacterial, viral and parasitic attacks on the major organs, it is very often that we will see dropsy symptoms in bad water conditions. We see this a lot in cold water especially when the temperatures change abruptly. And we see it in warm (like 90+ deg F) water situations as well. The stress of very warm water coupled with low oxygen potential can throw a koi's osmotic system out of balance. The result can be a significant fluid retention with the first sign of problems being pop eye. It would have been interesting to open this fish up and look at the volume and condition of the abdominal fluid as well as the condition of the caudal kidney. If the kidney is damaged, we can look to the usual suspects.. if not, we start to blame environmental factors.

Given your situation, I would not over react and start bombing the pond with chems and meds as this may make the situation worse. Let's see if someone starts to show signs of problems and work from there. In the meantime, add air and shade and make sure your pond bottom and filters are clean.
