Betta fish acting weird

[TitansBlood]

Hello everyone,
This morning I woke up to my Betta fish acting very weird. I noticed some food on the bottom from the day before that he had not eaten. after I saw this, I immediately isolated the fish. It has been a few hours now, and he is still doing this.
Is he sick, and how do I cure him if he is?
Or is this normal behaviour?
Video of my Betta fish is linked below.

Are there other fish in the tank with the beta? If not why isolate? I'm not a beta person but the fish seems to act VERY stressed. We will need to know your water parameters such as ammonia, nitrites, nitrates, PH and temperature. Any chance that you recently did a water change and forgot to condition the new water to remove chlorine/chlorimine?

No it's not normal. It could be poor water quality or an infection in the brain.

Test the water for ammonia, nitrite, nitrate and pH. Post the results in numbers here.

Wipe the inside of the glass down with a clean fish sponge. This removes the biofilm on the glass and the biofilm will contain lots of harmful bacteria, fungus, protozoans and various other microscopic life forms.

Do a 75% water change and gravel clean the substrate every day for a week or until the problem is identified. The water changes and gravel cleaning will reduce the number of disease organisms in the water and provide a cleaner environment for the fish to recover in. It also removes a lot of the gunk and this means any medication can work on treating the fish instead of being wasted killing the pathogens in the gunk.
Make sure any new water is free of chlorine/ chloramine before it is added to the tank.

Clean the filter if it hasn't been done in the last 2 weeks. However, if the filter is less than 6 weeks old, do not clean it. Wash the filter materials/ media in a bucket of tank water and re-use the media. Tip the bucket of dirty water on the garden/ lawn. Cleaning the filter means less gunk and cleaner water with fewer pathogens so any medication (if needed) will work more effectively on the fish.

Increase surface turbulence/ aeration to maximise the dissolved oxygen in the water.
