I am going to setup a 100g pond soon. I was wondering how many common and shubunkin goldfish could i have in it?

Out of curiosity, how deep is it going to be? Do you know your filtration system and all that? Better filters = more fish available. I remember reading about pond stocking levels on a big information site about ponds...

Also, this isnt from the site that I saw before, but this sounds similar to it:

To assess how many fish your pond will support, estimate its surface area and allow 60sq cm of surface for every 1 cm of fish (equivalent to 24 sq. inches per inch of fish). Since fish grow and breed, it is best to start off with around one-third of the theoretical maximum number. For example, a 1.8 x 1.2m (6ft x 4ft) pond will, in theory, support 360cm (144ins) of fish, equivalent to 36 individuals averaging 10cm (4ins)long, but, in practice, you should have only about 12.

Golden Rule - Your pond needs to have part of the area at least 60cm deep for goldfish and 1.5m or more for Koi if they are to be left over winter safely in the pond.

From here

I would continue to seek information on the internet and the advice of goldfish and pond experts, even on other forums with larger cold/temperate fish subforums.

I think it's about 1.5 or 2 foot deep.

I will be making the filter my self with a tall trash can with lava rock as the biomedia for the bacteria and filter floss to remove the leaves and stuff in the water.

But i don't have to worry about the pond freezing because i am in south texas and i haven't seen the temp get below 35 F in 5 years.

Cool. If you know the measurements of the pond, you should be able to do a tentative fish count using a conversion like what I posted before. (Like I said though, I'm not sure if that's a good one or not, and I would try to find some more to see if it is consistent with other people's guides)

Ok i will try to get the measurements of the pond monday when the LPS is open.

Thanks and I sure hope i can keep more then two goldfish lol

serissime

no problem. Have you considered how you are going to keep the tank cool? Ponds can heat up pretty significantly.

Paleofish

I will be putting it under a movable gazebo and It will be under the shade most of the day, Which should keep it nice and cool.

serissime

cool. glad you're a step ahead of me

Paleofish

Thanks!

What would make better pond goldfish for the size pond i am getting. Fancy goldfish or single tailed goldfish?

serissime

I would love to have a pond full of comets

I don't know what would be better for the size of the pond, but fancies are harder to keep outside

Paleofish

I just talked to a friend of mine and She said common goldfish need 50g of water each because they can get 2 foot


I guess if i want commons i will need a bigger pound or just keep TWO in the pond.

I guess i will just have to get fancies or a bunch of colorful cichlids because two goldfish just don't seem as nice as a school of them.

serissime

did she say that in reference to ponds? I don't know.... But comets really do get that big, yes. They also live for a long, long time

Paleofish

Yeah. But also commons are a bit "thicker" then comets.


I really can't get a bigger pond, So i guess i will just have to live with fancies or cichlids.

Amanda

I'd be wary of putting cichlids in an outdoor pond...

Paleofish

Why? People down here do it all the time and i have a heater to keep them warm in the winter.

Amanda

B/c I would think they'd be more susceptible to the fluctuations in a pond.
