[As Vanis gets closer to the tank, he'll realize that there's bits and flakes floating throughout the exhibit, some looking like fish food, some larger than others -- there are bits of what look like dark cloth and other, more organic-looking pieces of something.

Most of the sharks seem to be patrolling the bottom of the tank or lethargically circling about, but some of them along with smaller fish are gathered around a long, dark lump in the waters. Hm.]
