is it true some fish grow according to the size of their tank?

Answer 1

No, it is not true.
Well, actually, I guess it's not really a yes or no question. If you put a goldfish in a bowl it will not outgrow the tank because it will die first.
Everyone is using goldfish / koi as examples - people put them in bowls, they never grow more than 2", and then they die a couple months later. Properly cared for, though, they can live over 20 years and reach 12"!

Their adult size has nothing to do with their tank. It is pre-coded in their DNA. But, like all animals, if they are not properly cared for, they will not reach their full potential and they will die prematurely. Likewise, if you kept a child in a tiny, dirty room, it would not grow to its full height, even if its parents were both six feet tall.

It can be partly true. If you keep a molly fish in a 10 gallon instead of 20 gallon - which isn't ideal, but it's not that terrible, either - the molly definitely won't reach its 3-4" adult size... but it won't live as long, either.

Reversely, you can put a neon tetra in the biggest tank in the world and it won't grow to more than an inch or two.

Some large fish, however, that grow to 3-4 feet in the wild will never reach their full size in captivity, even if their tank is 10000 gallons - because in captivity, the water does not contain the same concentration of growth hormones that natural water systems do. But, again, they will not live as long as they would in the wild.

Answer 2

Fish kept in captivity rarely reach the size they would in the wild unless they are a naturally small species. Most will outgrow the tank if it is too small. Plecostomus and Pangasius cat fish are often in need of re-homing! Don't think that Gold-fish who remain small when kept in stupid Bowls or too small a tank are really OK because they are not! It is the cruelest thing you can do! They only appear to stop growing on the outside! The internal organs keep growing and become squashed together which causes many problems that don't show until the fish dies 'for no reason' No good fish-keeping site would recommend anything but a very large tank or pond! Some don't even recommend them as pets at all! If you are going to keep any pet then learn as much as you can about it before you buy and don't just take someone elses word for it not even mine! Go to the library and read books and visit as many web sites as you can!

Answer 3

The biggest and worst myth of them all! If this were true, I would have my very own great white shark and possibly a small shoal of barracuda swimming around my 55 gallon tank. Of course, this ‘fact’ which is all too often quoted by some pet shop staff, is totally untrue and has led to many fish being kept in cramped conditions. So where did this myth come from? Some fish will become stunted in a too-small aquarium. Although it appears that they have grown to the size of their environment, the fact is that they will have health problems caused by the stunting and as a result will have a much shorter life expectancy.
To prevent this from happening, always research the potential size of the fish you are getting and plan accordingly. Remember that most of the fish you see at your local fish shop are juveniles and are likely to grow much, much larger!

Also remember, most fish have an expected size range, however they can with proper conditions or luck, exceed this expectation.

Answer 4

Not true. Some fish will stop growing in size in a small tank, but their organs will still develop and grow. Because of that, your fish will slowly die if they are not given the space they need to grow.

Now some fish just don't get very big. Others will get very large. Do some research as to how big the fish you are interested in will get.

Answer 5

it's not that they grow to the size of their tank, thats a myth
if they are kept in inadequate sized homes their growth may seem to slow, but they won't stop by any means.

if it is say a goldfish being kept in a bowl, yes as other people have said, it will die before it has the chance to grow to full size anyway. mainly from stress and water polution from their poopy. the more stressed a fish is, the more susceptable to diseases they are.

what will happen however is they'll get stunted, get abnormalities, and die a painful death. not really what you want to put any pet through correct?

people should buy fish according to their tank size and not according to what they think is "pretty" or have been told is "easy". the smaller the tank, the harder it is to maintain and stock.

i could never work in a fish store, i would lamp every individual that came in asking for a goldfish and a bowl, or who wanted to put a baby oscar in a 10 gallon, or wanted 3 pangasius for their already overstocked 15 gallon.

oo i could rant forever on this subject!

Answer 6

properly, to a undeniable quantity, i assume you may say it incredibly is authentic. In a exact sized tank the fish will advance to their ability and be healthful and stay a protracted time. they gained't advance previous their organic ability no count how vast the tank.... So putting Neons in a 100g tank won't supply you 6 inch Neons. on the different hand, in case you place them in a tank it incredibly is merely too small, they gained't get as super through fact they are going to be stunted. they are going to be sickly and die lots youthful than they could. a super occasion of it fairly is the goldfish in a bowl. it could get to be 3 inches long and stay a million.5 to 2 years. difficulty is - it substitute into meant to get to be 10 inches or greater and stay over 30 years.

Answer 7

Actually this is not true. Fish continue to grow throughout their lives, regardless of the size of the tank. Their growth does slow naturally as they reach maturity but it never stops entirely.

However many fish excrete growth inhibitors as they get to maturity, and in a very cramped tank the level of these inhibitors can slow their growth, and in cases of younger fish even stunt their growth.

But please do not take this to mean that you can put in large growing fish into a small tank. You cannot. The fish will still outgrow the tank, and will lead a short and unhealthy life.

Answer 8

Yes. But be careful with this question! A giant danio will get like 1 inch in a 10 gallon but may get up to 3 inches in a 55 gallon. Cichlids will outgrow a tank no matter what and same with Plecos. Do research on what fish you want to get. I had a 55 gallon tank with nothing but community fish and when I gave them back to the pet store, they were still very small but were MASSIVE compared to fish from a 10 gallon. I would stick to small sized community fish to gain experience if you are concerned with question.

Example: Tiger barbs may get 4" but I have never seen a tiger barb get 4" in a 10 gallon tank....Ever. I have seen a school of 4" tiger barbs in a 125 gallon tank which was very cool.

Answer 9

It is true some fish grow according to the size of the tank.Such as sharks,if kept as pets.

Answer 10

Some.Not all. Tiger Barbs for instance grow to a max of 4 inches whatever the size of tank. But pencil sharks and suckermouth catfish can grow very big if the tank allows.Be careful.Read up.
