Thank you for the feedback men, that puts some worry to rest. All the tilapia I see are visibly fat, but none are over 3 or four inches long. I tested visibility today with a foot long white frisbee, and measured 54 inches just after direct sunlight stopped hitting the water (around 8:15 right now). I'm assuming the larger fish typically hang out deeper? Also, broodstock tilapia were added June 2nd if that helps with estimating how large the 2nd generation fish should be.
