Update - the tank is heated up.
And he is still surfing. But he stops every time I get his attention, it's like he is stuck in this endless job of glass surfing
Tank size: 55l
pH: 7.5
ammonia: dont have a test
nitrite: <0.3
nitrate: dont have a test

So the 18th of October I got my first fish a dumbo betta.
First day he glass surfed near his air pump which made me turn it off and he stopped...
