Yes, they have been thru the wringer alright. Scalding water, low O2, too much then too little light, verbal and visual abuse. They will be a rowdy crowd, but, remember, it's not their fault; they are a product of their environment.

Ewest, I gotcha. They were put in 55-60 degree water to take to artificial feeding, now some are big enough to start scarfing on live prey. But aren't they going in with adult male RES?
Maybe there is smaller forage, or will they continue to eat the pellets now even in colder water? Don't know much about YP, except that even when small they are scrappy and taste really good.
