i just bought about 30 brown trout fingerlings. most are about 2 to 3 inches. i have them in an old 20 long, which is too small. my intentions are too let them get a little larger before putting them in a pond at my parents house. there are some large mouth bass and sunfish in there so i dont want them all to get eatin. what should i feed the trout to make them grow quickly, and how big should i let them get before releasing them?
