One of the most amazing things I’ve seen in Waikiki Aquarium is placing what we would normally consider “not reef safe” fish in their reef displays. Below is their South Pacific display with the mighty Gigas clam. You can see the beautiful table shelf acropora coral happily growing and extending with coral eating butterfly fish in the tank.
This is a “smaller” tank (probably 1000 gallon) with anemone and clownfish display. Interesting enough- the tangs in this tank all look very beat up. They don’t look unhealthy, just really beat up, I am guessing from all the clowns (very aggressive and territorial) and probably tangs beat each other up among themselves.
