depends on what fish you have.
Most fish consist of about 60-80% water, but this can vary depending on the species, age, and environment of the fish. Water is essential for various biological functions in fish, such as respiration, waste removal, and temperature regulation.
They were formed with the receding glaciers during the ice age.

Yes - on average, and when fresh. As they age, off the tree, they lose moisture.
Fish need to be compatible, so make sure your breeders are the right age and size. Size matters, especially when it comes to tanks. So make sure yours is roomy enough for courting and that the water is fresh and clean. Stock your tank with the correct ratio of male to female fish. For some varieties, a little competition can be a turn-on - or a turn-off. Make sure your fish are well fed. When everything's done just right, the fry (newly hatched fish) will follow.

You Can Fish At Any Age
In many species of fish there are water parameters that have to be provided in order for the eggs to develop. These can be variations in water temperature, pH, GH, age of the water, colour of the water etc. In some cases the warmer the water the quicker they develop but it is also possible that in some species the ova (eggs) can be killed by water that is too warm.
