However, fish can protect their eggs so that the birth is carried out by keeping it in their mouth or protecting them with water bubbles.

The viviparous give birth to babies that have been formed inside their body.

The oviparous have the process of fertilization inside them like the viviparous, but instead of giving birth to young, they will lay eggs. The male fish would put the eggs inside, and these will develop there until they are ready to be expelled to the outside.
