Why dive here
With 71+ marine species recorded in the area - including barracuda and pufferfish - El Acuario offers some of Malpelo Island's richest diving. Water ranges 28-30°C, warmest September, October, November.
El Acuario is a bit of a tease, really. You drop down, and it feels like a nice reef dive, then you turn a corner and suddenly you're in a completely different world. We love the contrast here. You start shallow, maybe 10-12 metres, winding through these big cauliflower corals. It’s often buzzing with tiny things – bluestripe pipefish tucked into crevices, flat needlefish cruising just under the surface, maybe a curious blackfin soapfish eyeing you. But the real show starts when you push deeper, following the wall down. This is where we've seen bigeye thresher sharks making their passes, their long tails unmistakable. Dog snappers and red snappers school up in the blue, and barracuda often hang motionless, just watching everything. Keep an eye out for the smaller, more unusual stuff too; Pacific leopard flounders do an incredible job of blending into the sand, and we’ve spotted argus morays peeking from rocky hideouts. It's not the high-octane pelagic action Malpelo is famous for, but it’s a brilliant dive for appreciating the sheer variety of life. It’s a site that rewards a slow, observant approach, perfect for anyone who enjoys both the big and the small.
