I recall reading an article a few years back about a male fish that is
very aggressive with the females of their species. The agressively
mate with the females. The female fish hide to avoid them. I don't
recall the name of the species or even the region where they can be
found. I would like to know the region and the name of the species of
this fish.

Hi juanitag,

Thank you for your question.

The fish you're referring to is called a Betta (Betta Splendens) also
known as a Siamese fighting fish.

Breeding Bettas

"The male will blow an elaborate bubble nest when he is ready to
spawn. The female should be provided with a hiding place, as males may
become aggressive during courtship. Even with a hiding place, it is
common for the female to lose a few scales or have their fins frayed
during spawning.

When they are ready to spawn, the pair will display intense coloration
and begin circling each other under the bubblenest. The male will wrap
himself around the female who has turned on her back. As she expels
the eggs, they are fertilized and begin to sink. The male will scoop
up the eggs and spit them into the nest. From this point on the male
will tend the brood. It is advisable to remove the female, as the male
may become aggressive towards her as he tends his young."
