Hawkfish are indeed very cool. I've never kept longnose hawkfish (but have wanted to), but one of my first marine fish was a falco hawkfish that I was given by a Minnesota Aquarium Society member for the lab tanks. I'm kind of wishing we had some sort of hawkfish in the tanks now in fact (though I imagine they tend to eat shrimp?). I'll say that another real favorite of mine is the yellow headed jawfish, especially if you have a setup where you can have a group of them. And when we had these some years ago in the lab, they were favorites of students as well. We have a new science building in the works (we are a couple years before move in, but after YEARS of planning and attempts at fundraising, the fundraising has finally gone really well and the college now is committed - this is really happening now!). And it looks like we'll be setting up reef tanks in the new building (hopefully publicly viewable from the hallway this time, but none of the details are worked out yet ... and it is unclear at this time to me where the money for a new system is going to be coming from...). I do hope to be able to design this new system in a way that will allow us to keep a group of yellow headed jawfish again though - students and visitors would absolutely love this!
