Just got back from the LFS and they were all males

They said they will call their supplier tomorrow and see if he will sale them a few females. Guy at the store said a pair will run me about $200-250 depending on what the supplier wants for his females.
So, I've got my fingers crossed and in the mean time I'll be doing a lot of research and getting the tank ready!!!!
I also learned something new today....... You guys know the stuff in a can called "GREAT STUFF"????? It's an expanding foam that is used for many different projects...... well, they have a marine grade!!!!!! It said on the can "for waterfalls(and something else, can't remember right now)." Anyway when it dries it looks like the color of concrete. They used this in their display tanks at my LFS for creating the 3D backgrounds in the tanks. Very cool!!!!!! Never knew it existed!
