We wanted to add a flame hawk fish to our tank and got a really nice one from the LFS. He is in QT with a royal gamma and isn't playing nice. They get along just fine but a few days ago we discovered that he ate a big chunk out of the royal gamma. From everything we have read, most hawkfish are ok but we don't want to put him in our display tank for fear of him eating other fish. He probably needs to live in a tank with more aggressive fish as ours are more passive. We would trade him for a less aggressive fish. He seems to be very healthy and is a good eater when we feed. We have not treated him with anything in the QT tank yet. Let us know what you have to trade. Attached is a video. http://youtu.be/-yZ6NY6jjkQ
