Let yourself become surrounded in our Fish Roundabout. Ascend the spiral ramp to find yourself submerged in a sea of vivid blue light, with schools of fast moving open ocean fish on every side. Barracuda, yellowtail tuna and Pacific mackerel, are just a few of the fish you'll see in this amazing 100,000 gallon donut-shaped tank.
