70 Gallon/254L Pictus Tank

[phantomlink]

Right now I have a Pictus and a Striped Raphael in my 20 gallon ( they are still babies ) but have the chance to get a 70g/250l tank for pretty cheap and I was hoping to turn it into a catfish tank. How many of these guys would I be able to fit in a 48x18x18 tank? I know they get ~5 inches total length but I dont want to overcrowd it since they need numbers to be truly happy

I'd go with 6 Pictus and 3 Raphael Cats,

What if I stayed with 2 Raphael? Would I be able to squeeze 2 more pictus in the tank? I know the Raphael get larger and far wider then the Pictus
