Where do pet shops get the saltwater fish?

Most of the saltwater fishes are taken from their natural habitat and by a supplier and sold to retailers such as pet shops.

They are also bred in captivity for sale. Marine fishes that are sold for ornamental purpose are so colorful and are a beauty by themselves.

I always remember asking a pet shop this as I was curious and they told me that they are either caught from their natural surroundings or habitat and then sold to pet shops by those who take them from there and I was also told that they are also bred in captivity as well and then sold to pet shops.
