I would order one from a reputable shipper if I ever had the space for a single killer lol I've seen some at lfs that have nice marking but then you got a bunch of juvies with weird looking bodies and faces
I actually talked to my LFS about getting a Jardini Arowana and they told me "no problem." After dragging their feet on ordering it, I ended up purchasing one online. Arrived healthy and some beautiful orange in the fins, he's about 2 inches. Very happy. Going back to the same LFS to solve this Jag issue I saw they had a Jardini in stock. Lack of color (probably stressed) but fins looked chewed up, scrawny and just didn't look nearly as nice as mine. Very pleased I went online for that guy!
