Here are 200-300 3 week old fry in a 10g tank. I had pulled most of the fry from the parents just before they became free-swimming. The pair were exemplary parents up to that time and continued to try and raise the few fry left with them. The first video shows that even at that young age, they recognize the hand that feeds them - they are getting excited about their impending meal. The second video shows them "chowing down" on frozen baby brine shrimp. Pretty much a feeding frenzy!!
