well it seems totally weird but tonight i notice that one of my clown fish has a ripped fin. i dont know if it is from the larger clown fish being aggressive or not. i bougth them both at the same time and they were the same size (about an inch). the bigger clownfish (female ?) has really "bright" colors while the smaller one is pale and has a ripped fin. what can be causing this ?? he is just hidinig in the corner of the tank!!! dont want him to die!!
