Still in it's inaugural phase, visits are limited to guided tours. The number of fish is somewhat disappointing due to technical issues - which are being addressed.
Some of the exhibits are very creative. Especially impressive is the largest tank display where visitors walk (in part) below the fish. This creates an illusion that the fish are flying just above one's head or that one is physically immersed in the tank.
Our English speaking guide was extremely knowledgeable and responded to questions with patience and at a level which the questioner could understand.
The aquarium took great pain to explain how the issues are being resolved, and invited out group to visit behind the scenes.
I highly recommend the Jerusalem Aquarium.
