Yeah, pretty much, they stayed in a little gang!
They actually laid eggs up one side of the tank, at the front corner, but I never saw any fry.
You would see one swim up the side top to bottom, then it would come back to the pack and try to entice someone to follow. Usually getting a taker they would both then dart off and do the same thing, top to bottom. Over and over. Back to the pack, back to the corner. Pretty soon the corner was covered with white dots and like a webbing. Pretty cool to see!
