Interesting thought, I am betting smaller fry are more sensitive. Might be a good idea to be even more diligent when adding fry to a pond. When you're that small and there are already larger fish present who don't have that acclimation period to go through trying to eat you, the survival rate as to be awfully low. But even if 1 in 1000 survives to spawn, that's still 250 adult fish per box!
