Over Christmas my wife and son presented me with a couple of new Siamese Fighting Fish, or bettas. Betta is actually a fish genus, with many species, the most common of which is Betta Splendens. They are called Siamese Fighting Fish because they are aggressive nasty little fighters, and you can’t keep more than a single male in a tank or they will fight to the death. I nicknamed them Speedy and Pokey, because initially Speedy was quick and Pokey was fairly lethargic. But lately Pokey has begun to get more aggressive.
