StandoutExceptional marine biodiversity

Aquarium Wall feels exactly like its name suggests: a massive fish tank you can swim inside. We love dropping in here, particularly on a morning dive when the light hits just right, illuminating the wall that drops down to our max depth of 21m. It’s a gentle drift, usually, allowing you to just float and watch the show. The big story here is the sheer density of small reef fish, especially around the rocky ledges and coral overhangs. You’ll spot Jansen's wrasse and Exquisite wrasse darting in and out of the staghorn and honeycomb coral. Our favourite is looking for the Freckled Anglerfish, which blends in perfectly if you’re not paying attention – take your time on this one. Parrotfish are everywhere, chomping away, and we often see schools of Big-eye Trevally cruising by the deeper sections. It’s a relaxed dive, perfect for photographers wanting to capture macro subjects and juveniles, or anyone who enjoys a slow, observational drift.
