How big would Goldfish in a pond grow.?

Question

Well I have a small pond at home, probably about 8 hottubs in size (sweet unit of measurement eh?) and I surrently have 10-12 goldfish each about 5 inches in length in the pond. It is well maintained and has an abundant supply of algae. I was wondering how big the fish will grow and how long will it take them to get to that size.

Answer 1

Goldfish (carp) will in general grow as they are comfortable in their container. Yours sounds like a big pond (much bigger than a goldfish bowl, anyway), and so they will probably grow to be quite large, for carp - usually a maximum of 12 inches.

Answer 2

I have a friend who has goldfish in her garden pond. The pond is approx 13' x 15' x 4.5' (length x width x depth - approx 6000 gallons). When she got 8 goldfish two summers ago they were about 5-6 in long. She now has 3 to 4 times as many as they have spawned every year. The oldest are now almost 10 inches long and will grow to about 12 inches. So figure 12 inches after 2 - 3 years.

Answer 3

Hello, I am not positive. but let me give you some information from my past. Approx 50 years ago, there was a small spring fed pond, at a road side gas station. We use to get spring water to drink out of a small well there. any ways, the water from the well ran through a small pond. approx 2 of your tubs in size, and about 2 foot deep. there were around 6 gold fish in there, they were quite old. had the algae on their backs. Because of the amount of water flow, it did not freeze in the winter. None the less. the fish got to about 12 to 16 inch's in length. As in most ponds. it is not depends on the size but the abundance of food. Hope this at least gives you some hope for big fish. How long in length and time is still a function of the habitat. Thank you

My father has goldfish (koi) in his pond. He bought a bunch of "feeder fish"-- about 2 - 3" when he got them. There are 2 that are probably 14-18", and three that are about 8". They don't take long to grow that big. 2 or 3 years, I'd say.

Answer 5

depends on what kind of goldfish alot of people put koi fish in there pond but usally they can grow up to 30 inches and about 450 pounds they grow about 2 -4 inches every year so about years 8-15 years they also gain 50 pounds each year so about 9 years

Answer 6

A goldfish will grow as large as its environment allows. Indeed, a goldfish is simply a variety of carp. Personally, I've seen goldfish (swimming alongside carp) that were (conservatively) 20lbs.

Like carp, so long as you provide an abundance of organic matter for these fish to chow down on, they will accommodate themselves to their surroundings: pond size, other fish, amount of food available.

Answer 7

Fish release hormones into the water to regulate there growth in order not to out grow their surrounding.We mess this up by replacing the water in tanks hence the fish out grows its surrounding. Given this fact the bigger the pond the better and deep for koi.

Answer 8

Very cool unit of measure!! (nice imagination!)

Your gold fish will coninue to grow till they "fill" the space. A fish needs a certain amount of space to live comfortably... as your fish grow, their needed living space will also grow. When that required living space matches the size of your pond, they will stop growing.

I don't know if there's a limit, and I don't know how long it will take for them to grow to their "full" size... just make sure they don't freeze!

Answer 9

If they have enough room and food (not just algae) and time, they could grow to almost 2 foot. Look at Koi ponds for examples

Answer 10

Probably a couple years, pond fish are really just carp, and they get to be about the size of a trout i would assume.

you can google it and get a better idea.
