You can get flowerhorns from multiple people, like mrfh, ccooler, and few other guys from thailand. They then will go through a transshipper which i chose julie, does an amazing job, Then you pay only shipping fees in america and import fees (not bad, $2 a fry and $10 for a 3.5" one). If you contact them, they can give you good deals, and tell you what else they have for sale.
Here are a couple links,
Mrfh ( i have two of his and they are amazing looking.)

As for putting them together, no i haven't had any luck yet. so i wouldn't try it. You could keep two in a tank divided for breeding.
here is a video of some of the stuff i got in from mrfh and ccooler(minus the trimac). the first one has better color you just don't see it in the video, but pictures are attached to show off his color. Its a kml from mrfh.
