@Ituri -- The schooling fish are still there (but in much smaller number than when I first visited in 2021); however, it appears the leopard sharks are gone. I have not seen a single shark on any of my visits this year.
There are hardly any fish left and the Leopard Sharks are long gone. That's a real pity, as the sharks (although geographically inaccurate) were a real highlight back on my last visit in 2017. Also, there aren't very many penguins either. I'm guessing that there's a dozen of them, when in reality this exhibit would look even better with many more penguins.
