What species are present in your lake when you stocked your albino CC? They appear to be in the 8" range? Hopefully you don't have any overly large predators as you will have just wasted $50 as fish love to eat small albino CC. If you can, you may want to see if your supplier can get you some larger albino CC say in the 12"+ size. They will have a much higher survival rate and return for the money. I've had a hard time finding larger stocker albino CC so I will buy a few smaller ones and raise them in an aquarium or small outdoor pond for a few months to get them to the 14-16" range which one high quality feed doesn't take long before I release them into predator filled waters...
