how big is your tank? mine is 75g. i combined 2 biocubes when i upgraded back in april. the first hawfish (lighter colored one) i've had for about 8 months. i was at the lfs a couple of months ago and saw the other one. it's coloring is a bit unusual, much darker than it's partner. it was also much smaller. i did some research, asked a few people and decided to pull the trigger. it has almost caught up in size and has kept it's dark coloring. when i moved him from qt to dt, i used one of those net breeders for live bearing fresh water fish, put it in the big tank and kept him in it for several hours. once the first hawk stopped paying any attention to it, i released it and they have been besties ever since.
i say go for it! their behavior together is both fun and fascinating to watch. if they do separate, like during feeding when they are chasing food around, as soon as they are done eating, they seek each other out and stay together. i've heard that they have spawned in captivity although the young have never been raised successfully. when my actinics come on at night is when i see them dancing.
