They look just like Big betta fish, but smaller.
To determine if your betta fish is dead, observe its movement, breathing, and color. A dead betta fish may be floating at the top of the tank, have no movement, and appear pale or discolored. If you are unsure, gently nudge the fish or tap on the tank to see if it reacts. If there is no response, it is likely that the betta fish has passed away.

It can be difficult to tell if a betta fish is dead or just sleeping because they often rest at the bottom of the tank. Look for signs of movement or breathing, such as gill movement or fin twitching, to determine if your betta fish is alive. If you are still unsure, gently nudge the fish or tap on the tank to see if it reacts.

Well, if you love your Betta fish, then it should live by itself. But if you add another Betta to your current Betta fish's tank, then they will start a fight because Betta Fish are Siamese fighting fish and if one Betta is in contact of another Betta, the possible reason would be a fight between them two.
