BT161119A: Impression of the variety in a 'koi' grow-out tank at 22 weeks of age!

As you can see in the spawn-log (see link below), the fry in this spawn originally started out as blue/red, before most of them lost all colors and turned cellophane. Now they slowly start to gain 'koi' marble patches.
