Whats the story with fish growing in proportion to the size of their tanks or is it a myth?

I reckon growth is more proportional to amount of water changes done. Of course amount of food as well but the hormone released in fishes poo stunts their growth which is diluted dependant on percentages water changed.

I was told that a fish will grow to it's conditions i.e. if your tank parameters are spot on, the fish will grow to it's full potential - as opposed to the size of the tank being the limiting factor on growth. So a healthy fish should grow to the estimates you see in the books.

the size is determined by genetics and correct nutrition , the speed of growth by volume of food and tank conditions

Conditions in the setup also play a part.Some fish may just always feel unsafe and then not get their share of food .Other bolder fish in the same tank may just get all the food hence faster growth.I normally try to remove the weeker fish and rather find a more suited home for them.
