Scleropages jardini is actually Australian. I've seen jardini at a LFS near me; they wanted $85 for a 5" specimen.
Definitely not asian aros. Cheapest asian aro you can get from an LFS is ~$350. You probably saw an australian.I don't pay much attention to them, because I clearly would not be able to take care of them. But I know my lfs has a few jeuveniles for alot less then $300 bucks Canadian. I "believe" it was $65, like I said I didn't pay alot of attention. I just don't want a fish that will get that big....even if I could house it. But thats just my opinion.
