Male Beta fish are usually about 3 inches long when full grown and usually live two to three years.

Male beta fish have very long tails and fins. These fins are primarily used as a display. When the male beta fish feels threatened he will flare his fins in an aggressive manor hoping to scare off any rivals.

Male beta fish are often refereed to as Siamese fighting fish.

If male beta fish or Siamese fighting fish are placed in the same bowl or tank they will fight each other, usually until someone is dead. There has been much research into the reason for this. It seems it is due to the male protecting and reasserting a claim on his territory.

A male beta fish will begin his aggressive behavior as soon as he sees another male beta fish. This has been known to happen if the male sees his reflection in a mirror.

When the male and female mate it is the male beta fish that builds the bubble nest used to house the eggs of he female. In effect it is the male beta fish that will look after the beta young until they hatch.

When the beta fry emerge from the egg it is the male beta fish that will help the young betas to the surface in order to help them breathe.
