If it is a Betta splenden, they are anabantoids which means they can breathe oxygen from the surface of the water. this is because of the low oxygen levels in the muddy rice paddies of thailand.
Betta fish change color by there environment and the types of food that you feed it. If your Betta fish is loosing color that means that your Betta is sick.
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.
No, bettas are not chameleons and do not change colours.
If it is male it more than likely means it is getting ready to mate. If the bubbles are staying on the top the fish is just building a nest for the female to lay the eggs in.
no
Typically a betta will increase in colour, and in some cases change colours somewhat as they age. If your betta begins to lose it's colour, check for water quality problems or an illness.
The betta fish will see the mirror and then will be curious about it, because the mirror reflects the betta fish and they might think that it is another fish, so the fish will act differently.
