Carp In A Tank

[fish_lover09]

hello
A friend of mine wants to keep a carp in a tank but dont know what size tank he needs he wants to keep common carp hes planning on gettin them as small as possible and then when they get to big in my pond anyway questions are
1. how big of a tank will he need to keep 4 common carp
2. what does he need to keep the fish im know that u need filter am i right that u dont need heater for coldwater (could u get one and keep it low say bout 15degrees)
3. is it true that carp grow to size of the tank
many thanks for your help

just put them in the pond - - you will need more than a 100 gallon tank to house them for the first few months...why do this insane expense, space, and stress to the fish when you have already stated they belong in a pond? they can be added when young (may get eaten by adults)

yes, you do not need a heater

and the whole "grow to the size of the tank" is plain bulls**t.....
what happens is the fish is stunted....the fish's body is literally compressed, the internal organs continue to grow until their internal system ruptures of fails due to compression.

think of it this way, you can not put a person in a small room and expect to get a normal but "small person" - - you would get a person with a massively distorted spine from stumping over.

most goldfish do not belong in a tank at all....only in a pond. fancy (two finned) goldfish need atleast 20 gallons for ONE goldfish, and need double filtration.

why not just plan on buying a heater and plan a tropical tank?

Bad idea, tell him not to bother for the reasons posted above

i had no idead keeping a carp was so much hassle or strssing fish if u stick them in a tank, i keep marine and was only asking for a friend and i didnt want to lead him on so throught i would grab some info
Many thanks

Any scientific proof of this? much debated subject, not so much that the fish does not grow to it's potential size but on why. I personally think that the organs keep growing is incorrect, this is my opinion and not nessacary factual as you seem to state above.

Reread the question properly, will keep synopsis, but please see edit at bottom, thanks.

The stunting you see, spinal curvature, body distortion etc. is a result of a chemical interaction - resultant iteslf from the small water volume (rather than the physical dimensions themselves). Obviously, if placed ina physically restrictive environment, there will be physical abnormalities (e.g. placing fish fry in a small box, and allowing them to grow past the confines of said box).

The only members of the lining kingdoms that exhibit 'size or situationally' limited growth, are plants, corals, sponges and fungi. (e.g. a stunted Oak tree on a wind swept, nutrient poor landscape, a mighty Oak tree in a forest, and a tiny Oak tree on a water fall or as a bonsai. These are all 'the same' Oak tree, but can be vastly dimorphic in size.

This doesn't happen with anything but the simplest of the Eukaryotes, and so, is a myth. Factors that result in this myth being continually perpetuated include: "Small tank/small fish/small amounts of food", food availability/quality/regularity can result in slowed growth, or time-size differences between 'well fed and poorly fed' members of the same species. That is not to say that approximate reltaive size will not be reached, but that it may be reached more slowly.

i hope that helps answer the question a little more, this is the briefest synopsis, and there is plenty of old/new research available on the subject(s).

the fish's body is literally compressed, the internal organs continue to grow until their internal system ruptures of fails due to compression

there is nothing to support this theory, as stated only absolute physically constraining limitations would result in such 'compression' occuring, there is a potential minimal/maximal size for some internal organs, but this would remain 'relative' but not necessarily proportional to the animal, but nothing that could/would result in any kind of organ rupture.

View attachment carp.bmpHi, here is a carp I caught.....not gonna look too good in a tank!

How big of a tank do you think would be needed to fit 4 of these in?

a pond would be alot better.
