If the fish is actually 'floating' rather than the fish has simply positioned itself at the surface of the water as they normally do there may well be something wrong. Check water quality daily and replace at least 10% every day if you want healthy fish.
Fish do not normally "float around" they swim. If your fish is floating/sinking then it is probably dead.
The fish is either too full, or ill
If a betta fish is floating at the top of the tank, it could indicate a swim bladder issue, which may be caused by overfeeding, constipation, or infection. It's important to monitor the fish's behavior and water parameters, and consider adjusting its diet or seeking veterinary advice if necessary.
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.
nevermind, she died
When a betta fish is dying, it may appear lethargic, have difficulty swimming, and its colors may fade. It may also show signs of labored breathing or floating near the surface of the water.
No betta fish are carnivores.
other Betta fish and the bigger fish.
Betta fish do not eat fish.
it might be dead but if its moving tht means its alive and it has swim bladder disease
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.
A betta is a fish of the species Betta, especially Betta splendens, commonly known as the Siamese fighting fish.
