As long as all of the fish are under about 1.25" - 1.5" SL (not counting the tail) they're all still males. $350 for that is INSANE. Going price in stores around here is about $150. Bright green ones with purple tips can be had for half of that. I got my Rainbow BTA for free. I know some people.........I'll get a pic up later, the lights are out for the night.
