Betta fish, or also known as the Siamese Fighting Fish, is a member of the gourami family. They are native in the Mekong basin of Cambodia, Vietnam, and especially thriving in the water os the Chao praya river in Thailand. They are famous for their elegant and colorful looks because of their color and flaring fins placed on their elongated bodies. In contrast, it is their extremely aggressive and territorial behavior, which more often than likely result in a dead fish in the tank. Betta fish can live up to five years in captivity.
Their colors make them especially attractive to fish keepers with their flaring fins and brilliant colors ranging from blue, green, orange, red, violet to silver color schemes. Their color is also indicative of their moods. They would display a deeper shade when agitated and when they are starting to mate, colors and patterns would appear to signal their mates.
Why Do Betta Fish Fight?
Taking care of betta fish is challenging since they would often fight other fish with marking their spot. They are observing the difference betta fish in tanks and the wild; betta fish exhibit a higher level of aggression in captivity due to the fact of limited space. In the wild, they are less likely to fight for territory due to the broader swimming space. Betta fish often live in environments with limited food resources, resulting in their tendency to protect their places from other fishes.
Male betta fish are more aggressive than the female counterparts. Male bettas often choose their territory that is surrounded by rocks or plants. Once a fish, even of their kind, happens to trespass, they would fight until one gets injured, backs out, or dies. Their territories are especially important to them to obtain a mate. Their territory is one of the most important factors they have in getting a chance to attract a female and breed, and if a competitor appears, this will potentially dwindle their chance of breeding.
Another thing that causes tumult among your betta fish is stress. As a fishkeeper, you need to be sensitive when it comes to changes in water temperature, climate, and conditions since this can easily stress a betta fish. Even changing your aquarium decorations make betta fish antsy since they see it as a marker of the territory they have established. Also, male betta fish is protective and become aggressive once they have perceived that their bubble nests are in danger or even bothered.
Both male and female bettas are better kept apart, except for taking them in together temporarily when mating. It is because if they are put together in a tank, this will often result in fights for territory.
Females and males are only pair together when breeding. During the breeding stage, the male would create a bubble nest at the surface of the tank. When the male is interested in the female, he will signal the female to get closer by expanding his gills, fins, and twisting its body in a sort of dance. As they spawn, the female will drop eggs, and he’ll chase the female to prevent her from eating the eggs. Once it drops its eggs, it should be immediately moved back to its aquarium. The males serve as protectors of the spawnlings, ensuring that these have a chance of surviving and hatching. If a fish keeper happens to leave the female betta fish with the male, there is a high chance of the male going after the female and end up killing her.
Female betta fish display the same aggression as males though for different reasons. They are less territorial than males, and until establishing a hierarchy, females’ aggressiveness can observe. Among female groups or sororities, there would be 4 to 5 female bettas, and once set up the social order, this will pretty much make the females more at peace. If not, then the particular fish should be isolated for the time being.
Another fact is that the Siamese fighting fish is the result of centuries worth of stage battle breeding by the people from Southeast Asia, making this particular fish especially aggressive. Siamese fighting fish fighting is infamous for this, similar to cockfights, which will place the wagers of the fight. This culture still lives on until today.
Choosing suitable tank mates is also a must for betta fish. In particular, avoid pairing them with fishes that have large tails and long fins. They would be more accepting of Corydora catfish, clown plecos, Neon tetras, Harlequin rasboras, and Kuhli loaches.
