I believe this problem has the following choices:
a. It was hard to get the fish to breed and produce
offspring for the aquaculturist to raise.
b. Because the fish were stressed in tanks, they required
much more food, reducing the profitability of rearing the fish this way.
c. The fish had to be raised in a community with several
species of fish in the same tank, and they would attack and eat each other.
d. Marine fish are more aggressive than their freshwater
relatives and they tended to fight a lot, often killing some of the other fish
in the tank.
The correct answer is:
c. The fish had to be raised in a community with several
species of fish in the same tank, and they would attack and eat each other.

You described Toby as a pimple faced boy, so I think something might have happened with his acne. He might have touched/burst one of them and got the bacteria on the cheese. The bacteria colonizing the pore could have been cutibacterium acnes. They are there to generate enzymes to degrade skin, which may have made the customers sick when they ingested it. There's still lots of research going into the bacteria behind face oils and pimples, but this is the best answer i can give with this information!
