This instructable will teach you how to properly care for a betta, a beautiful and hardy fish ideal for the beginner. And unlike other ornamental fish-related instructables, this one will actually give you legitimate facts about bettas that will allow your betta to thrive.
Step 1: The Betta Background
The bettas we know today have long flowing fins and come in all sorts of striking colors, due to genetic mutations while breeding. Their long flowing fins is a distinguishing characteristic that is only acquired by the male, female bettas are generally smaller and have short fins. Male betta's aggressiveness is another trait that sets them apart from female bettas. Male bettas are much more aggressive than female bettas, that is why male bettas cannot be kept together where they are in contact with each other. Once in contact, they will instinctively fight to the death, hence the name siamese fighting fish. It is very important that the owner understands to respect this animal's trait, rather than to use it as a form of entertainment.
