Nice pickup. I love the TSN’s but I know that my 220 is too small to house them. That is why I went with a couple vulture cats. Even those might outgrow my tank and need rehomed at some point, but there is a chance they will be ok. I don’t feed heavily and their growth has slowed a lot since they hit 9-10”. My largest one is a little over 12” right now, and the other is right behind it. Here are a few pictures of them.

If I ever have to rehome my vultures, I might try a TSN after that, since it has become apparent that the ones available in the hobby are all culls that will not reach a very large max size. Plus, my LFS gladly takes in large fish to rehome them into better equipped tanks, so I can always go that route if necessary.
