Ornate aggression questions

  • We are currently upgrading MFK. thanks! -neo
I just purchased a large (16"?) ornate about three weeks ago, so this is based on fairly limited observations...

It seems to me that my ornate's aggression (and he is aggressive!) has a lot more to do with territorial defense than attempts to get food-- in fact, he seems more aggressive to my delhezi (the second largest fish in the tank) than any of the smaller, more bite-sized inhabitants.

Take it for what it's worth...
 
I'm not sure with Ornates, but I've seen fin nipping with Senegal Bichir. When it was newly bought, it did some damage to my goldfish's fins, but now, a few weeks after, no more aggression...
