Space Requirement For Goldfish, Ryukin,ranchus & others Options

[The Matrix]

Does that means that I will not be able to raise 6 pieces of TVR to grow more than 6 inches in the same 150 liters tub?

Ryukin is ryukin. Ranchu is Ranchu. Oranda is Oranda. Pearl is Pearl.

Each variety has its basic requirement.

I do not doubt that you or any other could raise some fishes to above certain size in a limited space. There are always something not stated within the simplifed statement. There are always some means to do so.

If one could find good and feasible method that provide an alternative to the fish basic needs, by all means, please do so.

There is no right or wrong, just improvements along the way.

I mean I've seen comets grow to full potential in a 100-200L tank.

Yes.

I don't know how much a ryukin can grow in one year, here is another climate than in Singapore.
But I can show you, how much fantail can grow, here in Germany in my 260 Liter tank.
I tested it more then 1 year with different fishfood at ~ 21 Celsius.
In the 260 Liter tank i checked it with 6! Fantail in it.

Every week I changed ~ 60% from water.
Today, I can say, the fantail, with better high digestibel extrudated food I use, better can grow up then in the test.

Here you can see it on my chart:

wow...

snowy, that's the standard way of making a record of growth on your ranchu, pearlscales, oranda, etc! A good reference for you in how to do it systematically perhaps!

AIYAH! Tidak lah now! I only keep ryukin - better start buying more big tubs *sobs* I always thought ryukin same as other fish - was intending to keep 2 in a 3 feet tank but so much for that plan! ARGH!

The issue here is that, is space the only way to get maximum growth for your goldfish. If not then, what other ways are there?

[desireless]

Yo Lim... your question is ummm... .

Space is not "the only way". It is a "requirement". And it is ONE OF the essential requirements. If someone is foolish enough to put his fish in a big pond of 5tonnes of water, thereby fulfilling the space requirement, and does nothing else, then his fish would still not grow well. He still need to feed premium food and change water regularly

BTW, if you're talking about ranchu....

Hello David,

I am confident that I will have a good number of high quality Tosai, but many more will have to be culled....  Very important is space and good water quality  !  This means keeping as less as possible.At the time being, I have about 200-250 in each pond (150 cm x 100 cm).  I do a 100 % water change every 4 days.

I have been breeding Ranchu for more than 20 years.  The most important what I have learned is the following :

Beautiful Ranchu = healthy Ranchu = good water quality = water changes, water changes, water changes, water changes...Regards,

Geert Coppens

Of course... plus good food. For eg, Geert uses JRL.

If you're talking about ryukin growth, then space is a compulsory requirement, on top of those mentioned above.

your question is really quite .... weird ... only way

with oxygen alone, you can't live till this age right ?

some grow up in kampong, some condo
some grow up eating fish and chips, some finding bites and pieces

they all grow up.

But could you assure that how u grow the only variety you are referring the same way as other varieties, some 600+++ of them ?

Chinese Goldfish, not just ranchu.

Hi Guenther,
You have provided a very interesting information on the growth of gold fish. Thank you!

all,

so the conclusion, is it possible for Ranchu Lover to keep his 6 TVR in his 150L tub, and have them grow 6 inch ??

rgds,

[cheangv]

Do you also include the water from the filter tank?

[IM A RANCHU :)]

wah? 500L? that is like a 5 feet tank for one baby ryukin? Or did you mean 50L?

3 feet tank is about 180 - 200 L depending on how deep / high

Lol!
That's pretty ridiculous...
Some people who breed goldfish commercially say 1l for i inch for each fish..

your mate, Joe

The topic is about raising very BIG Ryukin. Not other types of fish and not 1000 fish to 1 inch in length.
I had 4 ryukin in a 40 gallon tank and couldn't get any of them over 4 1/2inches (10 to 11cm). Then I started a large green water set up and my largest ryukin is 6 inches or so around (15 to 16cm).
Ryukin grow at a very slow rate. If I'm not mistaken they are the slowest growing of all the fancy goldfish.
I believe this is why people make a big deal out of big Ryukin it takes alotof space, time and work to grow a Ryukin over 5 inches.
