I bought a knifefish the other day that was labelled "Brown Ghost Knifefish", well it definitely isn't that species and it closely fits the pics I've seen of Asian Knifefish. I am wondering if it will be able to live its life out happily in my 55 gallon tank. It's a very cool fish and I'd like to at least keep it til it gets too big for my tank if I won't be able to keep it for its life.
