Testing the ride could begin anytime after the trains arrive & are installed, but the aquarium is scheduled to be finished mid April. It should be early-mid May before they can begin to move the fish into the tanks due to strict water condition inspections that take weeks to complete (even if all tests are passed on the first go round). Once the fish are moved into the tanks it takes another 4 weeks before they are settled enough to allow the ride to be opened. So the projected opening date is set for June due to aquarium, not the ride readiness.
