Your Betta fish most likely has a condition called Pop-eye. It commonly results from damage to the eye or bacterial infection. Heres a website to get you started... http://www.fishjunkies.com/Diseases/popeye.php
He's probably constipated or you fed him too much. did he eat recently? try not feeding him for a few days and see what happens. if that's all that seems wrong and he;s still acting normally, he should be ok. Probably just ate too much or he's constipated.
It's because it is sick or pregnant if it is pregnant that means your going to have babies in a couple of months and in that time you should take care of your betta fish but if she or he is sick you should put some medicine in that tank so your betta fish won't die!
Most fish will take a bite of food, then spit it out and eat it again. This breaks the food up into smaller pieces. It's like chewing, and is normal behavior.
The "air pocket" on the underside of the Betta fish is actually it's stomach.
Most likely she's full of eggs...you could try you hand at breeding her if you like.
Feed it 1 scoop a day
Its probably pregnet
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.
Female beta is a murderer.
Male betta's are more colorful then female's
From a female Betta. Then the male Betta fertilizes them when they breed together.
Your betta fish is a female if she has smaller fins than an average male.
If they are not too old and the female is ready, then they will mate.
She breeds with a male Betta Fish.
it depends i have a male with a female betta, in a 2.5 gallon tank,they get along, i wouldnt risk it, no
the female betta fish are released from a vent while a male embraces her
If you would like to know what gender your betta is, look for the egg spot. (for females) It should be a small white cloud between the head and body. If your betta has one, it's a female. If your betta doesn't have one, it's a male.
Np, but they will bite. Yes, they will fight to the death.
betta fry are not born .they hatch from eggs laid by the female which the male fertilizes.
