Tank divider, what and where to get?
 

I have a 48-inch long tank and I would like to divide them into four smaller ones. (like those we see in the local fish stores sometimes) Could anyone give some advices on which material I should use and where I can get them? I want a non-transparent ones so the fish won't see each other. Thanks for any help.

Petsmart sells tank divider here, they are white with tiny holes, the fish won't see each other and have bracket to mount in the tank.
