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.
not unless they are sick
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.
A male betta has a long flowing tail while a female has a short tail
Betta fish derive their color from refraction within a layer of translucent guanine crystals.
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.
I would probs say a Betta fish because of their color
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.
Yes how do you think the multicolored bettas came to be the fish are still bettas no matter the color they are.
no
other Betta fish and the bigger fish.
Betta fish do not eat fish.
No betta fish are carnivores.
Just watch how they interact and if the betta is being aggressive isolate him. Bettas can be with other fish as long as the betta is a different color and there arent any fish with similar fins.
