Yes, we also were in that popular (and supposedly knowledgable) store in Hayward, and saw all the sharks for sale. Hope they make a nice profit so they can build that big new store.
I saw this thread here a few days ago and decided to open a similar thread on another board. I thought it was really pathetic that someone would display a Nurse Shark in a 72-gal tank as an inspiration to the "Beginner Aquarist," as Juan puts it on his site.
