The last time I bred kribs, it was for the $$$$. That was back in the late 1950's. They had just shown up in NY and I got them from a retailer who made me a great deal "you can have these but any young you get, I get first dibs when they reach 1" in size." He paid me $.50 each and I was delivering 100 or so a week. Not bad for a kid considering most dads made that each week and I was doing it after school. I guess I would sat the average spawn I got was close to 70 or so. Since those were early wild imports, spawns today could be larger or smaller. I have also seen red kribs and blue kribs but my heart will always go to the wild colors because of my experiences. Later, over many years, I farmed freshwater angels and had a coral farm.
