A mandarin goby swam its way through a glowing blue tank while clownfish flitted in and out of anemones. A few feet away, students salted a 1,200-gallon touch tank that is expected to soon house groupers and other sea life, as well as mimic tidal flow. Seahorses swam in a corner tank. In an opposite corner swam four whitespotted bamboo sharks. A 925-gallon coral reef display stood waiting in anticipation of creatures.
