I have a question for owners of both species. I know they're both pretty much logs until feeding time but which would you say is the more active of the two? Or is it the same? Yes I realize they both have to be kept alone in a huge tank. I'm trying to decide which of the two I want to keep. I am leaning more towards the Wallago Attu because I like their sinister smile but I see more Wyckii for sale. Which of the two would you keep and why?
