is it true that a fish kept in an aquarium will only grow in proportion to the size of the tank? e.g. a Bala shark kept in a 80 liter tank will be smaller than one kept in a 160 liter tank?
yes it will no grow fully. it will aslo die very young
not a good practise. but it would outgrow a 80ltr too. its just plain cruel.
internal organs will not grow properly and it will die at a very young age and live a very unhappy short life.
