Hes not overly agressive, but he some times chase other fish away if they get to close. I have never seen him in any big fights. The comfusing thing is that when i baught him, the guy that sold it to me said it was a red top zebra. The next week when i went to the same store he had changed the lable on the tank i baught it from to Cynotilapia afra.
I think its the nicest fish in my tank so i really want to get some females for him
