I finally got not 1 but 2 rainbow sharks. They've been on my want list for a while. They are 1.5 inches a piece, both boys, and both together in a 10 gallon qt. After quarentine, one will go to a 20 gallon with my female bettas and one will go to the setup I am doing for brichardi cichlids. They are so cute I've been staring at them all day. The one I named Xander chases the other occasionally, but not all that much, they both have distinct territories already. I posted the unnamed shark's picture in the gallery.
