I have been told a bigger home, with lots of plants and decoration to give them places to exploreAlso, warmer temperatures can help.
Maybe he's stressed out? Some Bettas cannot do well in bigger tanks, try moving him to a smaller tank, also is he seeing his reflection and flaring a lot?He is in a 29 gal by himself lol
