This depends on what you mean by backflips. If it's just a way of swimming, but otherwise your betta swims upright and normal most of the time, then it's just being a fish.If your betta is stuck upside-down, it could be related to water quality or a swim bladder issue.

It is alright if your axolotl swims around at the top of their enclosure. This may however signify that they need more oxygen and that you should clean the tank more often.
You may be able to train a betta to swim through a hoop with the information provided below, but it doesn't necessarily mean that it will be successful, or last in the long term.Put the hoop in the water and put a piece of food on the other side.When she swims through the hoop to the food, let her eat it and do it again.Keep doing it until she can go through without the food there.If she swims around the hoop, put the hoop in between her and the food again.Keep doing that until she gets it!Tip:Always let her have food after she has done it, even if the food wasn't in the tank to begin with.
