Fin and gill flaring in Betta's is part of what is called a territorial threat display. If a male Betta detects a threat in his territory (usually, a bowl of fish tank), then he will puff himself up, trying to look as large and threatening as possible. It is a way to protect himself and his territory from other fish.
Most males do that because you are intruding their territory.
I had a male that did this anytime a female came around him or his part of the tank.
------------------
This is a completely normal event, in that they flare to warn males to back off (I've observed my females do this too)and to impress their mate with their size, and to tell other fish that this is his/her territory.
bettas "flare there gills because they feel a threat or they see a female or something they think is female
the betta splendens (splendid warrior), is, as his name indicates a warrior, basically he is a fish with a bad attitude problem.
This is a threatening pose. It is trying to make itself look as big as possible in an attempt to frighten and chase the other Betta away.
It is usually because the male is mainly the dominant one and is saying: "Watch out, I'm bigger than you and I could kick your butt."
Kissing in male betta fish is a display of agression. It is a form of fighting.
To get her to mate.
His gills will flare up.
Yes, the "red thing" is actually called a membrane. Bettas will flare out their gills and membranes when he is feeling threatened, especially by another Betta fish.
Mainly for territorial and mating purposes. Bettas are very territorial and will attack any fish with bright colors and large fins. Especially other Bettas. Bettas flare when threatened by opening out their fins and extending a 'beard' from under their gills.
It means he hates you. Bettas flare their gills out when they're trying to scare another betta away, or to impress a female with how large he is.
Bettas flare to scare other fish from their territories or to attract a female.
Not neccessarily. Some Bettas do have very dark gills.
Female bettas can be colorful, but males tend to have larger fins that they flare, as well as more vivid colors.
Like almost all animals, bettas can be male or female. Adult female bettas typically have shorter fins than adult male bettas, and are often less "showy" or brightly colored than the males (though colorful females definitely exist). Female bettas have a white bump on their stomachs, called the ovipositor-- this is where the eggs are stored, and where they are released from when mating occurs.
No bettas are fish not mammals. Bettas have a labyrinth organ which enables them to breathe air when there is not enough oxygen in the water to sustain them. Here are some things that separate bettas from mammals Hair. Bettas have no hair or fur Scales. Bettas have scales, mammals do not Ability to breathe through gills. Mammals do not have gills, bettas do Egg laying. Bettas lay eggs, mammals give birth to babies without shells that are able to breathe by themselves
Typically they will flare their gills at each other and begin swimming around each other very closely, it's actually difficult to really see that they are fighting. My suggestion, don't keep 2 male bettas in the same tank.
The male will puff up his gills to scare the female by looking bigger. If the male betta looks straight at you when he is flaring, it makes him look bigger. He follows the female to scare it away.
Some bettas just have dark gills, even the white ones.
