Betta fish can be from 2 to 4 inches long when fully grown.
A body length of around 2.5 inches is a well grown male.
A betta fish is anywhere from 1 to 2 inches.
a betta bowl is about 12-15 inches in length and about the same in height
While there are no real studies about the length of the attention span of a betta fish, it seems to be about the same as a goldfish. That would make a betta's attention span about three minutes.
Betta fish grow to be an average of 2 inches from head to the beginning of the tail.
a long time
Depends what fish you have, if the fish are colourful and have long fins then it'll probably bite it to death, every betta is different.
A Male Betta will grow to about 2.5inches of body length and a Female will grow to about 2 inches of body length. A Betta is fully grown at about 6 to 8 months a Betta is very old at 30 to 36 months.
Bettas are not a sport fish so records of size have never been kept. A well grown male Betta has a body length of around 3 inches.
Bettas are dumb as rocks. If you put another betta, any other anabantid like a gourami, or any long-finned fish in with a betta, the betta will fight it because he will think it's another betta. If you put a short-finned fish in with your betta, they'll live together peacefully.
No betta fish are carnivores.
