they're 22.45$ each. they eat small stuff like brine shrimp. I got a male (the ones with the lateral stripes along their length. If you have the room, you could consider getting a couple of females and a SINGLE male. this will cause the male to "flash" more often, really showing his colours and spreading his fins. I just have a one guy and so far he's pumping his fins up and down pretty often. I am very happy with my purchase.
