no as long as there is water conditioner/ purifier in it
their life spawn is 2 years
Yes as long as it is not chlorinated.
A betta fish is anywhere from 1 to 2 inches.
Betta fish can be from 2 to 4 inches long when fully grown.
Betta are airbreathers. So long as the ammonia and nitrates are okay, you don't need filters on a Betta tank.
up to 4 months
Betta fish, guppies, tetras.
To the best of my knowledge no one keep those kind of records. Bettas are mature at 12 months, past their prime at 2 years old and ancient fish at 4 if they live that long. I have a Betta fish that is now over 5 years old because I change the water once a week with 2 gallons of purified water and I add about 20 drops of Splendid Betta Complete Water Conditioner to it. Using the water conditioner is a MUST to ensure that your Betta fish will live a very long life. I also feed my Betta fish 4 pellets of Hikari Betta Bio Gold once a day in the morning and 1 pellet at around 7pm.
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.
