This flaring behavior is common among male bettas when the fish defend established territories or mating partners. Fortunately, the fight is mostly limited to displays of flaring and spread fins.
Betta flaring is perfectly normal , but the behavior is not always an expression of anger. When a betta flares, this may also be your fish stretching its muscles. With that in mind, fish keepers typically see bettas flare when two males fight with each other. For example, the betta splendens, or Siamese fighting fish, are selectively bred to be aggressive, and flaring helps the fish appear larger than life.
Betta fish detect color visually and may easily spot a male betta. Many fish keepers think the male betta is looking for a fight, but conflict is the last resort. The confrontations between two male bettas in the wild rarely end in death. One male usually retreats in defeat. The confinement of a home aquarium presents different challenges as the habitat is small, and there are not many escape routes for the fish. The general rule is only one male betta per aquarium in case the two fish are overly aggressive.
If a male sees his reflection in a mirror, the betta responds by adopting an aggressive posture. There are many other reasons bettas flare gills, and sometimes this behavior may happen after a water change! This showy ritual is what Siamese fighting fish are known for, and modern strains are far more belligerent than wild bettas. The fish initially try to deter one another with ritualized displays.
The bettas raise fins and flare gills to make themselves look more prominent. Betta fish need suitable tankmates, or the environment may collapse. New hobbyists must watch the community to ensure the betta is not chased, or a fish does not try to nibble on the beautiful fins.
The betta's gills may flare from stress. Hobbyists need to observe tank behavior closely to ensure minimal flaring behavior occurs. The sad thing about this show of aggression is that as the male bettas increase in size, their aggressive display also follows suit hence the need to jar the male bettas separately upon commencement of any form of aggression.
The females can tolerate each other; so they can be left to grow together for as long as possible. There are different betta strains and the aggression varies across the kinds of strain. Some beta strains are quite peaceful, accommodating and can live in groups while others are not. Most times, the largest male or female betta fish takes this position.
For as long as the Alpha fish remains in the tank, there is usually order and serenity. This balance is distorted when there is an introduction of new sets of betta fish. I find the betta behavior quite interesting and I know you do too. You guessed right! These bettas are quite a handful and they possess unique personalities. They can express depression in different ways, they might refuse to eat and decide to starve to death it can be that serious.
Expression of personality difference can also be observed in their feeding styles and methods. While one betta might happily feed on a brand of pellet, another might just simply refuse to even have a look at that same brand of pellet.
They are fast learners; they can easily recognize their breeders and look forward to their return from work because they enjoy getting the attention of any sort. They can get so used to your hands such that they can come swimming towards it on sighting it. Their ways are really beautiful; they also know how to roll up some bags of tricks! A Betta fish can puff out its gills when it wants to flare them.
The puffing out of the gills exposes its membranes. It mostly does this puffing out as a response to intimidation or as a means to enforce its presence. The flaring of the gills exhibited by your betta is a response to a stimulant which might mostly by the presence of another male betta in the same environment. The motivation is different, though. Its purpose is to make one fish stand out as the better or more fit mate. Scientists have studied flaring for decades to determine why it occurs.
Even Charles Darwin pondered the question. Female Bettas often have a small amount of the male sex hormone, androgen, which can explain why they will also flare sometimes. The researchers observed that two fighting males reach a point where their actions become synchronized. Genetic analysis showed similarly enriched genes.
It could reflect the consequences of selective breeding. However, it opens a new path of investigation. Other research delved into the sex-specific hormone theory. Scientists exposed male Bettas to antiandrogen drugs. These increased bold behavior, regardless of the dose.
This evidence suggests that something else is going on to trigger flaring. The answer may lie with another mechanism to explain this aggressive behavior. Researchers looked at a different hormone called serotonin. This chemical activates in the brain and other parts of the body, including the digestive system. It also plays a role in both mood and sexual function.
The scientists administered a drug that would ultimately lead to higher levels of serotonin in male Bettas.
