The LF in the pic was purchased as a jumbo for big $. Your LF will be fine for a few years in a 180. Once they hit the 3ft mark their growth really slows down.
My LF ate, primarily, crayfish (since I owned a crayfish hatchery). I also fed him earthworms, ramshorn snails, and FW mussels. When I could find them he also received grass shrimp. During winter (when bait supplies are low and crayfish young are scarce, I fed him a variety of Kensfish sinking sticks and catfish nuggets. I never fed him feeder goldfish or tilapia due to the conditions these species are raised in.
Unfortunately, I no longer have my albino. He died during a relocation when my company transferred me from one state to another.
