Don't worry about it man. My Discus are always fighting. I have been thinking about getting it on video. Most people have a hard time believing in healthy Discus. I think if they are slow and listless you have a problem.
I could buy a 200 gallon tank tomorrow but I don't have the room right now.
I am actually very interested to see a spawn.
So far the younger ones fight more then the two adults.
By the way what do you think about a white pigeon and Blue diamond spawn?
