[Delphinus]

They're a pretty docile fish for the most part. They are a predator of pods so there will be skirmishes with other fish that are well. My sixline had a problem with him and beat him up the first day, the second or third day the flame beat him up back and they've gotten along ever since. The problem there is that my sixline is a bully, not the flame hawk. The sixline was a problem to my potters angel as well until the potters fought back and won (basically he needs to have the snot kicked out of him to learn to leave a fish alone). He actually killed a mandarin. So sixlines are a potential problem, but I'd say the flame hawk is not a problem,

However, hawkfish are also reputed to be able to take down ornamental shrimp, so if you have shrimp (cleaners, peppermints, fire, etc.) that would be a consideration..
