Two Male Banggai Cardinalfish
 

So... I love my fish selection. I have two Banggai Cards, 3 Chromis, 1 Coral Beauty and 1 Lawnmower Blenny... but ive noticed my cards chasing each other, and at feeding time if its flakes the one will chase the other off... Should I worry about this male battle going on.. or should I do somthing about it.. and if so.. what are my options???
