They look just like Big betta fish, but smaller.
Betta fish are usually multiple colors like turquoise on the tail fin and blue on the body and purple on the top fin. They can be one color like red and light red and dark red.

light
Betta are social fish. There is nothing wrong.
Well, Yes and no. Betta do like LIGHT to be able to distinguish night and day, they also need the warmth, but you can use a heater. betta fish do need light, but it is not good to keep a betta in direct sunlight as it may increase the temperature byy far too much. so just keep it in light at day, or get a lamp.
The life cycle of a betta Fish goes like this: *They hatch *They live *They die
yes but do not pick fish that are soooo small like minnows because your betta will EAT HIM UP!

Bettas are dumb as rocks. If you put another betta, any other anabantid like a gourami, or any long-finned fish in with a betta, the betta will fight it because he will think it's another betta. If you put a short-finned fish in with your betta, they'll live together peacefully.
