I have a friend who is building a pond. It is almost complete so she is beginning to look into getting fish for it. How many fish could you put into a 1225 gallon pond, and what kinds of fish are pond compatible? Please give me any advice that I can pass along to her.
 
There are many goldfish species that can live in ponds but depends on what country you live in as some can't survive things like the english winter and stuff and if the pond is likely to freeze over in winter like it does in so many places in the uk, if it doesn't have enough depth you may not be able to have fish like mature koi karp and things.
How deep is the pond and what country does your friend live in? Is your friend more of a koi karp person or a goldifsh/other coldwater fish person?
 
The pond is only 2 feet deep. She has another pond that is 200 or so gallons that she has one goldfish in. My thoughts were for her to get goldfish, but she wanted to know how many was a good number to keep in there? We live in the US. Ohio. She's never had a problem with the water freezing too deep in the other one, so that shouldn't be a problem.
 
As far as i know its going to be too shallow for koi karp as they can get to many feet long, so golfish species may be your only real option. Do you know what species/types of goldfish she has in her other pond and wether she doesn't mind more of the same or similar fish or is she looking for somthing totally different?
 
I'm pretty sure they are just regular goldfish. I'm not familiar at all with goldfish. She loves her other one, so I imagine she wouldn't mind getting more. How many would you suggest?
 
Really it depends on filtration, but goldfish will grow big in a pond and you could be looking at fish around 18 inches long. I would give each fish around 30 gallons but really you need Bri or another pond keeper to tell you how many.
 
Bump for an estimated number.... She's becoming anxious and I don't want her to go out and just buy without info :no:
 
I think a rough estimate would be 40 depending on what species of goldfish you get but that doesn't mean go out and buy 40 goldfish all at once- if you did that you would get an ammonia spike which would be bad for the fish. I'd say add 10 goldfish a month max, also if you friend stocks the pond more slowly she is less likely to get bored of them as soon and if she wants she can stock it slowly enough so she can still be buying fish for the pond for a year or so.
Many goldfish can live up to 40yrs so you don't want to get bored of them a year or 2 later and rehome them as otherwise that would be unresponsable and its not often goldfish get a pond the size of hers very often so she would be doing a good thing if she kept them for as long as posible :) .

if did that 10 a month just for 2 month make 20 and leave it for couples year u never know u may have newborn goldies etc
 
id go for no more than 20-30 and add them a few at a time

40 fish are going to produce a lot of waste (more as they grow)

as stated it depends on how good the filter and pump are its best to add too few than too many

you can see how the filtration system copes and add more fish but as soon as the filter starts to struggle ,take a couple, out

its nothing to do with depth but surface area the bigger the surface the more fish you can add ,koi will need at least 3ft but id set that as an ideal depth anyway

you could go for commons and comets with a few other fish types mixed in but certainly not more than a dozen koi as these reach 30" in length
