I received these photos with a request to identify and judge the quality.

What do you say?

Charcoal black with silver mirror scales.

Hi Admin
Some or other german pantsergoi.

Very friendly old monster. Pansergoi? German?

Hi Cronje

Neville is pulling your leg, you can't believe a thing he says.

It is probably a Doitsu Ginrin Kagami of the Karasu family?

Kagami – an old koi variety with mirror scales on both the dorsal and ventral sides


Karasu – a totally black koi, often tinged with a blue haze

Té laat! Het hom/haar klaar Nazi gedoop

I bought 8 very small Koi +- 4yrs ago and put them in a large pond which gets its water from a fountain - 100 000l or so. Now I sit with 400+ koi and the large ones are eating me off the planet. Not many Koi farmers round here so, could you advise as to how much one could get for a fish like that? As I'm not a pro obviously I dont want to rip ppl off. The smaller ones are 10cm - 20cm+. Thing is there are light blue with perfect black markings (like the black ones) along the dorsal fin and white head and some nice-ish ones. I would just like a pointer please.

Dankie Cronje,

Ek dink "Nazigoi" is n heel gepaste naam vir hierdie vis. Ek het 3 in my dam, een is mooi gunmetal grey, Ander een is donker groenerig (ongelukkig nie n midori goi nie). laaste een was redelik donker charcoal maar begin nou blouerig word van bo af. Hulle is baie mooi visse en groei nogal vinnig.

As ek reg is het Kevin Harrison in n vroeer Koisa oor hulle geskryf, sal vanaand kyk en julle se.

Ai Paul julle kan darem party goed glo man.

Hi Cronje,

Jy moet maar n bietjie onder jou pelle werk en hulle kry om damme te bou man.
Ek wil my nie uitlaat oor n prys nie hoekom probeer jy nie n pet shop in Polokwane nie.
As jy van hulle moet ontslae raak moet hulle tog net nie in n eco systeem vrylaat. dan liewer in n oop pan of quarry gat sodat die voels in jou omgewing hulle kan enjoy.
Paul sal seker hier meer waarde kan toevoeg maar ek sien al die dealers kla dit is stil niemand koop juis op die oomblik.
Maar hoekom plaas jy nie n paar fotos miskien soek iemand iets wat jy het.

Neville: wont let them free. Apparently against the law. I already have "Hamerkop", some King fishers and a giant King Fisher gooi-ing a sushi at the main pond but they dont seem to make a dent in the number of Koi I have...anyway, if all else fails off with their heads. I'm 160km north of Polokwane; transport for me would be a nightmare. Deep bush. In Louis Trichardt - Makhado the only pet shop there doesnt take Koi longer than 8cm so Im buggered. Maybe I should start breeding Fish Eagles/King Fishers now. Then I can stop worrying and call all my Koi Kamakazigoi and those who can really not stand the heat, Harikirigoi.

Hi Admin

Is it not also called a "Yorigoi" By the way the article was not by kevin some other gent wrote it, will post tomorrow, my internet is off posting from friend.



Ok The chaps name is Bernie Woollands See Koisa No210

Que? I might be lost. Is this koi speak? Have not the faintest idea where we are going with this.

thank you all for all yr input. Much obliged.
Question: on the waterfall/water feature at my home pond, there are funny little worms clinging(quite tightly)to the cement and stones. They are about a mm to 3mm in size. Black with a hard exosceleton. What are these? Are they a threat to my Koi and if yes, what do I do? I have a 10 000l pond.

Suggestion, why not post a few pics of fish you want to get rid of, if there is like 10-15 fish, transport etc would all make sense.....maybe post them under koi for sale, and ask for bids, subject to getting 10-15 together....

As soon as I find out whether those things on my waterfall are parasites or not, I guess I wont be getting rid of them right now. And if those are parasites and I dont quickly do something about it, they'll getting rid of themselves for me. Thanks for advise though.

Yet another Q: How many Koi in size range 15 - 20cm long can I keep in a pond which holds 10 000?

10 000l that is.

10 would be the safe nummber to keep as they can grow fairly large fairly quickly in the right climate.

However if you filtration is very good and you have a decent setup with decent turnover you could always go up to 15.

Hi Cronje,
I think you are already way past this no.?
anyway I think Chris is correct longterm but a bit conservative for the short term. If I am correct you have a fountain feeding this pond, now it will depend on how much water this fountain are replacing per day and you can then make an assumption. Bit difficult for us to say, without knowing.
Please give a bit more detail and maybe also some pictures.

Hi Neville,
you're quite right, I AM past 10 and even 15 fish in number. There are 400+ Koi in my home pond. 7 large ones i.e. 35 - 55cm. According to you guys that's about the limit, right?
They are the mama's and papa's of the 400 or so youngsters that share the 10000 litre pond with them. A wild guess tells me that about 5000litres drain away during the day(winter) and it gets fresh water 24/7; i.o.w. 5000litres of fresh water everyday, right?
I had a parasite scare yesterday but luckily it turned out to be just that. A scare. The fish all seem very happy but still I guess the more space the better. The water almost never clouds and I have only two small circulation pumps for the water feature. The manure and leaves that build up at the bottom, I remove with a contraption that works like a vacuum cleaner. Water temp average 25 degrees but never below. In summer it gets way warmer. I'm pretty sure the water quality is good; it tastes great anyway...
Camera is in for repairs but soon's it's back, I'll post some .
Thanks for the advise so far from y'all and keep it coming.
Lekke weekend.

With a daily 50% water change, the normal principles do not apply to you.

1 fish per 1000 liter is normally good for the long term, bearing in mind that the fish will probably reach 60-70 cm each, leaving you with 65cm/1000 liters.

The top end hobbiest, especially in the UK and America, believe in up to 2500 liters/fish, but then we are talking about optimal conditions for show quality.

The general rule of thumb is 66cm / 1000 liters at any time. In your case, a total of 666 cm, provided that you take out as they grow.

However, with your daily water changes of 50%, I think you can host at least three times more.

Jissie dankie Paul. Dis baie goeie nuus. Koi is mos eetbaar. Wanneer hul te groot begin raak gaan ek hul slag en op "pension day" aan die ou mense op waterpoort verkoop ; )

Ja maar gelukkig is hulle nie lekker en sal jy dus nie eitlik takers kry nie. Daar is beter vis as jy will vis eet.

Droog hulle leiwer uit, maal dit en gebruik vir diere voeding.

Ons ouens hier glo nie eintlik daarin om ons koi te eet nie hoor.

Maar ek stem met Paul saam jy kan heelwat vis onder daardie omstandighede aanhou. Maar soos ons almal weet n fontein kan gaan staan of die vloei kan verminder en dan sal jy beslis al die vis oornag verloor.

Neville, eks nie ernstig nie hoor. Grappie soos jou PanserKoi. Sal nooit 'n koi dood maak nie" euthenasie" indien nodig.Sal wees soo om my hond a-la-Chinese te eet. Moerse dankie vir al jul hulp. Het gelukkig 'n generator vir Load shedding. Lekker Sondag verder.

Hi Cronje

Bly jy se dit ek het nogal verwag dat jy gek skeer jou blikskottel. Jy het my amper my gasket laat blaas.

Jy moet ook n lekker dag he daar in die bosveld.
Maak n mooi koedoe vas en bel my.
