I recently got this Showa and placed it in QT. A month later I moved it to my main pond, and a few weeks later detected a problem with it's left pectoril fin.
I treated the fin with a salt paste, and returned it to the pond. A few days later I noticed that it had started isolating itself in a secluded corner of the pond, and then moved it back to QT pond, after spraying the fin with Terramycin. The salt level was increased to .4%. I've noticed that the fleshy part of the body adjacent to the fin is also inflamed.
Any advice?

Other fins seem fine

Antibiotic injection now before the underlying ulcer on the body forms a hole which will leave a scar.

Very bad, should be kept in a heated pond to recover or it will die.

Anti Biotics in this cold weather probably wont work or work very slow.

Terramycin I dont like, I would rather smear it with PP paste, and cover with antibiotic powder. Carefull trimming will also help.

Maar waar is die dam Dr. nou, (maak seker n sandfilter skoon).

Hi Jack,

Sal jou skakel!

Ek sien party mense is sommer baie groot bek nadat hulle 'n paar uur in die "kliek" se geselsskap was..............moerse slim ook skielik

Gaan leer spel Doc. Sarkasme pas jou glad nie, jy F@k dit op.

Hi, and thanks for the replies. The advice was rather disconcerting, so I took the Showa to a vet at Onderstepoort. The following was done:
Skin scrape and gill clip - no parasites found.
Diagnosed were:
Petechial haemorrhages on gills and belly.
Swollen bruised lesion behind left pectoril fin.
Injected with 1 ml Nuflor and 0.5ml Vitamin C.

Need to return on Friday for 2nd antibiotic injection.

I also checked the water in my QT pond, and all seems to be OK.
pH > 8.2
Nitrite > 0.0-0.1mg
Ammonia > 0-0.1mg

Raising water temp, as suggested by Jaco: Any suggestions as to how to do this? I have the QT pond with about 2000l in it - above ground PVC (as the vats at shows). I tested the temp today, but I think it could be faulty - reading 10 degrees. Would a PVC cover on top of the net help? More frequent water changes with borehole water, which is warmer than pond water currently?

A petechia (pronounced /pɨˈtiːkiə/, plural petechiae /pɨˈtiːkɪ.iː/) is a small (1-2mm) red or purple spot on the body, caused by a minor hemorrhage (broken capillary blood vessels

Yes covering the pond with plastic will help a lot, leave an area open to breath.
WOW Frans, ek is beindruk lol

Hi Jack

Thanks for giving us the real experts findings, much apreciated. Sure we can take note. Please tell us again on Friday. Looking again the fish does not look good at all, in a way happy you took it there. Hope it pulls through ok.

Hey Jack

I think you are on the right track. I had the same problem as you and got some brilliant advice on the forum. Surely it helped alot and will never forget about the helpful info on the forum and the fish I could save but the important part is to remember to get down to the problem and use the correct medicine that will be effective for that fish.

I had many problems for some time but been lucky the last few months. Some times it to late to do anything about it but I hope you have good luck and that the Koi will be happyy again soon

Hi,

First of all there are not many Vets that specialize in fish in South Africa.

Dr. Neville Marias was one of the few that did, but sadly he retired about a year ago.

Florphenicol (Nuflor) is from the same spectrum as Chloramphenicol ( Frequently used in case of ascites) but is oil based, it’s really slow to release from the oil, therefore we can use a mush greater dose and use as a one shot approach or one weekly shot ( Nuflor 30% or 300mg/ml)
Chloramphenicol ( Globenicol) is an effective antibiotic with a broad spectrum.
Nuflor should not be injected into the pectoral muscle, it will cause localized necrosis.

I am afraid and of the opinion that without taking a blood sample of Jack’s Koi, and by using Nuflor some guessing took place with its treatment.

I really hope the Koi will survive.


PS. This is only my unprofessional view, so please keep the panties dry!

yes pieter, dr marais retired, but dr paul elshove is still there,
the few times i have needed help paul assisted.
