Thanks, guys. I really think Knife fish are so cool . . . I have alot of creek rock to arrange areas in the tank, it's a 125W, so the footprint is great, six feet by two feet. Had that in mind . . .
Sorry about MTS, it's shorthand for Malaysian Trumpet Snails. I had wanted some, never could find, then all of a sudden they showed up in my quarantine tank--had to have been in some java moss. It's cool to watch them hatch, and they hang at the waterline, about 1/4 inch, and the fish will just snarf them up. A few wrigglers make it down to form shells!!!!
