Yes you can but they will try and attack each other and may hurt themselves bumping against the glass. Also you can put a male beta (with the big tail) in the same tank as a female beta (no big tail) without using a divider. Also you can put two females together but they dont look as nice as the males.
deffo salt watercoz i have a tank full of siamese fighting fish and i keep them in saltwater
A Siamese Fighting Fish can see its reflection in a mirror.
a sword and a shield ?
Siamese fighting fish lay on the bottom of the tank because they try to play dead
i have a half gallon bowl for my betta fish and he has plenty of room
Yes, you can just not have 2 male bettas together.
It could be a bowl but i would say an tank
yes i leave the lip on the lid on the tank because it will jump out \
The only fish you can keep in a 5 gallon tank is one betta (Siamese fighting fish) on it's own as that is a very small tank.
They need a 5+ Gallon tank and you can only have one in the same tank.
I would recommend either a Siamese fighting fish (betta) or a molly. Both are very easily taken care of, and are gorgeous to watch.
Take them out of the tank and separate them. They'll most likely eat the babies.
