my two oscars that ive had since they where babies are starting to all of a sudden lock lips and fight. this happens not all the time just like every other day if that. all i have in the tank is 1 silver aro, 1 JD, 1 GT, 2 little silver catfish and a little wild oscar. any idea's
It's not really a big deal. Most likely they're just trying to either pair up like PMK said or are just establishing a pecking order. Beautiful fish, by the way!
