The experienced aquarists' basic rule for keeping any kind of fish (Including Anabantids) is "1 inch of fish needs at least 1 gallon of water". A fully grown female Betta splendens will be around 2 inches long. Ergo she will need a tank that will hold at least 2 gallons of water. Assuming that the tank will only be filled to within 1 inch of the top and will also have at least 1 inch of substrata (gravel), you will need a tank that has a nominal holding capacity of almost 3 gallons. Some people would advocate a smaller tank but IMO they are ill-informed and do not have the welfare of the fish foremost in their mind.
it looks like they have a big bubble in their side
big around the stomach just like a human!
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.
Bettas are egg layers so they do not get pregnant. A female Betta splendens will grow to around 1.5 to 1.75 inches and a male about 2 to 2.5 inches.
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.
