ok thanks....how big will the rainbows get between fall and then that next spring time. i know the water temp will stay below 65 during that time and also would any of the other fish in my pond be a problem to the rainbows. i have big catfish and some 6-8 lb large mouths, and crappie...but there are alot of baitfish and minnows in there too for food. would the dead rainbows hurt other fish in pond too when they die or do i need to try to get them out in summer time. also how many would be recamended to put into pond in fall
