What a great photo! Gosh, they are big already.
Well, I confess that I had a mishap that occurred in my hatchery. We had a very big rainstorm a few weeks after my fry hatched, and the hatchery got caught under the lip of my capstones. So since it was unable to rise as the water level in the pond rose, the fry all got pushed up and were released into the pond. And, of course, nature did what nature does and took care of business.
So I learned something valuable in how to situate my hatchery next spring.
