Not 100% positive but two males in one tank most likely will lead to aggression unless your tank is huge. I know you can add a male and females but two males i'm unsure of. Mine was from LA also but if they weren't listed as paired, good chance your getting two males. (not 100% sure)
PLEASE COVER YOUR TANK AND OVERFLOWS WITH THIS EXACT FISH. He gets spooked and DARTS right into my netting. If i didn't have a cover he would easily clear the room. He is not jumping, just gets spooked and takes off like a rocket. He was rescued twice from my overflows until i learned they needed covering also. He is a free swimmer all over the tank and extremely peaceful. (heard other stories from other people) GL...
