I agree. My kids orthodontist has a 2000g eliptical tank in their office. They had a 3+ foot black-tip in there and all he did was swim in a right-handed circle. It got to a point where his left eye was all messed up from rubbing on the acrylic and they got rid of him. I think they donated him to Mote Marine Laboratories, which is local. They had him for a couple of years, and as impressive as it was to see that shark, being a hobbyist, I couldn't help but feel bad for it. Also have a Sohal , Clown and Achilles tang ( which are awesome btw) and some other fish, but the shark did nothing but circles.
a thriving reef will give you years of wonder and amazement, whereas you watch the shark for about 10 minutes, and you've seen it all.
Good advice X.
