If you do get them, be very mindful of their dorsal fin and barbs, they both tend to get stuck in nets VERY easily (I have found that using a gladware or some type of plastic tub to catch them when the need arises works very well). A guy at my LFS also said that if you somehow manage to get stabbed by the barb, it hurts... a lot.
But they are gorgeous fish with awesome personalities, and the first fish that everyone goes "WOW" at. When they quarrel with each other or are annoyed, they make weird buzzing noises.
