As well, I would like to create a thread gathering all of the species of PB sometime in the future, with pictures of all the different species and listing a minimum tank size for each. But I'm not experienced in that regard but would like to try to gather that information. May make that a long term project for myself. But as I said, I think it would be better to have first hand experience to have the right to create a thread like that. On facebook I have been told that a 96 x 30 x 24 would house not just Kelberi but others like Xingu, Orinoco and Intermedia. Not sure how true that is though. I had written off PB because I had thought they could only fit in a pond.Yep, that's exactly what many of us have been saying here and on other similar threads. About 24" though you can see some disagreement even among experienced member. I personally would not -- in fact I'm kicking myself now for going with 32" instead of 36" wide tanks. A 24" will be ok for maybe a couple of years, but then you'll have to dish out big bucks for a whole new tank.
All of that said, I honestly cannot again in good faith recommend any kind of Arowana to those new/newish to the hobby -- others might disagree but imho it's kind of like getting your first driver's license and going out to buy a Porsche or a Dodge Hellcat as your first car -- best to ease into, get some experience and then move on to something more challenging, just my 2 cents.
