Wow,I remember the first blacktip I've ever seen was in a store that I used to work in years ago .The shark was about two feet in length,the tank was a 180!
I hate to even think of what became of that poor creature.

What would you suggest in terms of length of body multiplier for slow growing, non-ORV swimming shark? Smoothies or zebra shark, for example? Just as a rule of thumb - curious what'd you suggest.
