Absolutely not. Parrot fish are tropical fish and aggressive, kois belong in ponds and not tanks because they grow very large, goldfish need 15 gallons each (fancy) or 25 gallons each (single tail), and a 'sucker' is indeterminable as there are numerous types of 'sucker' fish

There is no fish in the world whose head would grow separately apart from the body may be you need to change your question.
No, the only fish that do that is the parrot fish.
There is one way I know to protect fish is by building fish farms. There are large tanks that grow fish and control and regulate their growth, their food, and the water they grow up in. There are many advantages and many disadvantages as well.
It seems these laboritory made abominations (parrot cichlids) reach maturity at about 3 years old and can live for up to around 10 years. Being artificially manufactured they can not be bred successfully though.
it wont grow as large as if it was in a larger tank
