First of all, they're BOTH bettas. 2. if they're both males that's just animal cruelty. Some people....
Yes they will.
Male crowntail bettas have the large finns commonly associated with the betta fish with a small difference in the edges of the tail. Females have very very short fins with the crowntail edges
They would not fight anyway. Male Bettas will only fight with male Bettas. The Convict Cichlid is a much larger fish than the Betta and has a much larger mouth in proportion too than the Betta so I would assume that if they were to fight the Betta would not stand a chance.
because he doesnt want to and you get to close to the bowl
CLEAN HIS WATER AS SOON AS POSSIBLE!!! Ammonia is produced from the fishes waste. It is toxic and will kill your Betta fast!!! Do regular water changes.
Some male betta fish are not as aggressive as others.
male
Yes. Betta Fish do change their coloer every now and then. Or if you have a male, he will change his coloer if hes chaseing a female Betta Fish. Or if he sees another male Betta Fish.
yes
Male Betta's are solitary. They cannot be placed with other fish. That's why they are known a Japanese fighting fish. They will kill other fish for territory.
None are recommended if the Betta is a male.
She breeds with a male Betta Fish.
