All fish in video with ruler were hatched 3/7/18, and the video was taken July 14th "” so, 4 months old but they're now 5 months and a little bigger. Two varieties hatched the same night so I put them together. The black and white with normal markings are Darwins, and the rest are from a pair of Mochavincis.
So... all the white ones are from the Mochavincis, and, oddly, VERY few (1 or2?) with anything resembling the parents markings.
