For the best health and lifespan of a betta, you should consider something that is at least 2.5 to 5 gallons and can have a small heater (bettas need a water temp of 78F to 80F), and a low flowing filter on it whether that be a small internal filter, or a small HOB (Hang On Back).
for one betta the minimum is 1 quart of water (four cups).
A small fish bowl should be fine for one betta fish.
most of the time but with betta fish no they can live at room tepature
Because, if they are in a small cage the Betta will stop growing. But, the organs will keep growing and the fish will die a long and painful death.
Betta fish need filtered and oxygenated tanks just like other freshwater fish. Pet stores that tell you that Betta fish don't need much room or filtered tanks are either ill-informed or just plain unethical. Too much current flow isn't healthy since Bettas like slow moving water. If you are putting a plant inside a tank with your Betta (and not keeping the Betta in a vase with a plant growing out of the top and the roots growing into the Betta's space), any freshwater fish-friendly plant is good. Just make sure that it is soft so it doesn't damage the Betta's delicate and beautiful fins. Don't put a Betta in a vase with or without a plant growing above it. Also, don't keep them in tight containers or small cups. This practice is cruel and inhumane!
i have a half gallon bowl for my betta fish and he has plenty of room
Room temperature.
i have before. and i just kept them in a class room
No. Beta fish are very sensitive.They die easily because they are extremely suceptible to diseases, and if the temperature of their water is slightly colder than it should be, or if their water is not sanitary- has too much waste (pee or poop) in it- they die. I know this from experience. The same is true with goldfish.
A 1 gallon tank could have one betta fish, but you will need to be diligent about changing the water on a regular basis. The smallest tank that should be used, even for a betta, is a 2.5 gallon tank as it at least gives the fish swimming room.
Yes, but this is very cruel. All fish need room to swim and to grow and although people have successfully kept bettas in tiny containers, this doesn't mean it is right. Also, bettas are anabantoids, which means they need to breath air, so they need a decent amount of surface where they can go to breathe. if you want a betta, go for at least a 2 gallon tank - the fish will be much happier, more active and more colourful.
Beta fish just go to the bathroom like we do just in their thank or bowl.
beta fish are very territorial if there is plenty of room for both of them in a tank they will just leave each other alone and another reason is that they haven't had to compete for food
Depends on how big it is.
