How many MFK's have one of these guys? Is it not a truly beautiful catfish?
There is wide variance on maximal size - quoted from 24" (Orinoco) to 39" (Amazon). A minimum tank size, assuming you don't know the precise origin of the fish if you are lucky enough to get one, would probably be 10' x 3.5 x 2.5 (approx 548 UK Gallons / 2487 Litres). Most I have seen are primarily silver with very slight blue hues, however the speciment in the pic, owned by a UK hobbist, is the first I have seen with so much blue in it's tones. It's in a 12.5' x 4.5' x 3' (5000 litre) tank!
