Do these categories of fish exist?

[BenSow]

The type of fish that:

1)Grows only as big as its environment
2)Grows big no matter the size of environment
3)Will experience stunted growth if not given a large enough environment

So? Do those three categories of fish exist? Give some examples too, Thanks

No. 1 and 3 are vaguely similar but both do exist.

1. No, the Pacu I've rescued have proven it... the most obvious and recent, a 22 inch fish from a 55 gallon tank. It literally couldn't turn around.

2. Same answer, I guess.

3. Same answer, I guess!

I don't think fish STOP growing... maybe slow down... but they still grow.

I think alot depedns on whater chemestry and the typ of fish. iv seen soem fish grow ridiculious sizes in small tanks. for smaller tnaks fish will genrealy ghrow slower and tis is generaly due to the fish being less active,less food, and the build up of nitrate and hormones. this tell the fish its inviormtn is too small to withstand growth........ wich isnt a good thing at all. can cause ltos of problums because the fish bodey wants to grow but wotn develop properly. not to say that cant live for years soemtiems in the condition.

so to anser your question yes and no hashaha.

I have read koi is no.1, pacu is considered no.2 and arowanas, plecos and a lot of fish is considered no.3

a fish will grow to his enviroment depending on the fish and health, a badly kept oscar, with little care in a 20g will grow and keep growing but most likely be stunted. ive also however seen huge fish in a tiny tank but the water was kept well, and good filtration and lots of water changed and the fish was in a small tank but grew to normal size and porportions.

any fish that is in any enviroment that will nt meet its needs for growth will suffer even if it does grow and get "big" the internal organs will be damaged and the life span will be drastically shortened.

My uncle had a freshwater shark that I've seen get upt to 2 feet in a 100 gallon and after 8 years only got about 6 inches, After keepin my own tank i realized he didnt know exactly what he was doing but he's kept a number of fish in that tank that lived a number of years so it must have been enough to keep them alive.

I know that feral populations of goldfish which exceed their bioload for the pond they are in will stay small. Not that's it's a healthy thing, and their lifespans are certainly shorter, but it does happen out there.

The bottom line for this thread will probably end up being:
Any fish kept from attaining its optimum growth and vigor is suffering, no matter what the cause is. To what degree they suffer is up for debate.

So is this right: A pleco in a 10 gallon can grow big if the tank has a killer filter and a driftwood. A pleco in a 200 gallon without filtration but has driftwood will stay small.

Are those statements correct?
