[Gosling's Exotic Fish]
Colorful fish dart amidst the greenery in a large tank along the far wall of the shop. Above the tank, water trickles from tier to tier down a roughly carved blue sandstone waterfall, finally tumbling into the tank. Light reflecting off the surface of the water sends flickering patterns dancing around the room. You also see a sign, a low marble slab with some stuff on it, and a polished driftwood table with some stuff on it.
Obvious exits: out.

A sign reads:

We offer a variety of exotic fish and other creatures in sealed aquariums. These are balanced systems which do not need feeding. All aquariums have four different types of fish, while the fishbowl has but one.

We have also obtained exotic pets from the mainland, housed in sealed terrariums. Marvel at life that grows outside the waters that shelter us -- a perfect educational gift for children with inquiring minds.
