My LFS told me that this bp is a female. what do u guys think. can they also get along even if they're both male? http://www.youtube.com/watch?v=uMwJjTsrpa4

Nice bp...ask the lfs if they see the fish lay eggs before. The video is clear but it's too far away...can't really see the vent.

If the male is not attacking the bp, they can live together whether it's a female or male. If he starts to attack the bp, then you need to remove it. Looks like they are happy together...the bp might be a female. Won't know it for sure until it lays eggs.

The chance is high that its a Male it has pointy fins =(

Very pretty but it's too far away. You need to get close to the vent.

ok. i took another video. i hope this helps.

she finally layed some eggs but the flowerhorn is eating the eggs. not sure what to do. i think im just going to leave it alone and wait to see what happen.

Well then she's a female. Next spawn should go better.
