Just because they do it doesnt mean it's right. You hear of people keeping Yellow Tangs and Porc. Puffers in 30 gal. tanks...this is the same difference.
Let's say the 10' long tank is only 18" front to back. How is a 40" Cat Shark going to be able to turn around? Sure, it'll enjoy the 10' length, but not if it cant turn around. There arent too many rays, available in this hobby, that are gonna stay smaller than 18" round, either.
Even if the tank happens to be 24" front to back, that's still not good enough.
