My Cambodja Betta splendens male has from time to time a little short 'sparring' with an enemy in the mirror... (that allows him to maintain good health condition - he will not be anemic and inactive)
Here betta's in a breeding tank. Just after putting the mirror in stronger colours, wider fins and raised gill covers can be easily noticed. Well, this time he didn't try to bite the opponent in the mirror... ;) (that sometimes happens)
wow, your betta has some great attitude gud luck taking care of him. You may want to visit my channel got some betta too.
