Do fish have babies or eggs?

The eggs develop and hatch into larvae (baby fish) without any help from the parents. Most larvae are eaten by other creatures, but a few survive to become adults. Some fish, such as the bullhead, look after their eggs or young. This improves the chances of the babies surviving, so fewer eggs are laid.
