that isnt the fish that just 1 off google lol
but it called that in the shop and i recken it will die soon if i dnt help it it being keeped with silver dollers at the mo i think i will get it i have found out that it can grow 2 2ft at the most
i'm not sure what you were saying w/ your google comment. should be fine in there w/ those 2 for quite a while. the way you tell is perruno have less hard dorsal fin rays than longibarbus, but both look almost identical. perruno are a lot more rare and therefore worth more so LFS' call them "perruno" to get more attention, from what I know and have heard
i don't think they are aggressive, they will just eat anything they can fit in their mouths...typical catfish and typical that they should eat quite a bit and not be too picky. I've never kept one, so take my advice with a grain of salt, lol. I have a couple LFS that have them and I am SO tempted to buy one every time, but they will get to 3' more quickly than I am prepared for at this time.
