Congrats man, I see you finally got what you've been wanting for a long time. You should feed them some rosy reds now since they are too small to eat bait minnows. Just watch how fast they strike the feeders, it's like a missle.
Hey let me know how you fish are in a group like that since I only have two at the moment. I hope they're more active in a group because my walleyes lay on the gravels all day without moving much. At the petshop the walleyes they have are always on the move so it's wierd how they changed on me. Maybe because at the petshop there's always people and my tanks in my bedroom and I'm barely home.
Keep us updated, and yeah I hate the way they look when their skinny. I'm trying to beef them up too, it's working already and the shape of their body is better now.
