Betta fish are well known for their flashy colors and extremely aggressive behavior (Doutrelant & McGregor, 2000). They are an excellent model species for studies of both intrasexual and intersexual selection. If placed in the same enclosure, male bettas will fight, especially if they are protecting a territory containing a bubble nest meant for a receptive female (Noble, 1938). This is an example of intrasexual selection as males are competing against other males for territory, females, defense, and so on. It has also been found that female bettas will “eavesdrop” on fighting males to select the winner, which is an example of intersexual selection (Doutrelant & McGregor, 2000). If receptive, the male will attack a female to determine her readiness to breed (Noble, 1938), thus again indicating intersexual selection. The male must test her readiness to breed, thus determining if she is receptive, fit, and worth the energy it takes to produce sperm and copulate.
