I've had the flamehawk for about a year now....very curious little fish. Everytime I'm either working in the tank or sitting looking at it, he is right there staring & watching. Quite entertaining fella. I haven't seen too much aggression from him in the past, but he does own the right side of my tank. The Goby is now on the left side. LOL Tonight, the Goby was letting one of the cleaner shrimp clean him, but not aggressively working on the bite. He looks good and have been watching to see if the flamehawk is after him. He isn't that I see, but I guess he'll be OK as long as he stays on the left side of the tank!
