Aquarium — Fish-Dense Reef & Sea Turtles at Havelock Island (Swaraj Dweep)
Aquarium earns its name the moment you descend. Rather than swimming toward the fish, you are swimming through them — schools of snappers, damsels, and butterflyfish filling the water column on every side, the reef constantly in motion with coloured life. This is what an aquarium feels like from inside the glass. Located on the southwest coast of Havelock Island, approximately 20–25 minutes by speedboat from Govind Nagar (Beach No. 3), Aquarium is a shallow bommie reef that offers the most fish-dense and most vibrantly lit diving conditions of any beginner site on Havelock.
The site's defining topography is scattered coral bommies — individual coral pinnacles rising from a sandy base at 2 to 15 metres, each one a self-contained habitat with different species, different coral types, and a different community of residents. The protected southwest position keeps surface conditions consistently calm, and the site is one of the most reliably accessible boat dives on Havelock in variable weather.
Overview of Aquarium (Quick Facts)
About Aquarium Dive Site
With the reef beginning at just 2 metres, full sunlight penetrates all the way to the sandy base at 15 metres throughout the morning dive window. Aquarium is increasingly popular among Havelock's dive community, known for the best natural light and colour conditions of any dive site on the island. Hard corals that at 15 metres would appear blurred by blue-shifted light here display their full colour range — vibrant greens, purples, and oranges visible without torches. For underwater photographers, Aquarium offers composition opportunities in natural light that most Andaman sites simply cannot match at equivalent depth ranges.
Topography
Aquarium is a fringing reef on the southwest/west side of Havelock Island, partially protected from easterly winds, which is why surface conditions are consistently calmer here than at exposed sites. The defining topographic feature is the bommie structure: scattered coral pinnacles rising from a sandy base at varying heights, separated by sandy channels and open patches. Unlike a continuous reef wall or slope, Aquarium's bommies are individual structures, each one a self-contained habitat with its own species composition. The bommies are arranged in a loose along-shore pattern, creating natural pathways that guide divers from shallow sections progressively deeper without a fixed route.
Best Time to Dive
Aquarium is best diveable from October to April, with dive slots from 7:30am to 1:30pm. The early morning slot offers incredible conditions and the best natural light angle for photography — sunlight strikes the reef surface at a lower angle in the morning, creating directional shadow and depth on the coral surfaces. Visibility typically reaches 15–20 metres, and water temperature stays 25–30°C year-round.
Marine Life at Aquarium
Sea turtles are among the most reliably encountered species at Aquarium, sighted on the majority of dives, grazing on seagrass in the sandy sections between bommies or resting on the coral formations. The shallow, clear water makes turtle observations here among the most visually rewarding on Havelock.
The bommie structure supports a dense and varied fish community throughout the depth range. Clownfish occupy sea anemones across the shallow bommies, moorish idols move between bommie sections with deliberate grace, and named grouper species — peacock grouper, black-spotted grouper, and yellowfin grouper — hold position near the larger, deeper bommies. Moray eels extend from crevice gaps, parrotfish graze noisily on coral surfaces, and lobsters shelter in bommie bases.
In the sandy sections between pinnacles: nudibranchs, stingrays resting flat, and on occasion marble rays. Schools of snappers, trevally, and jackfish fill the mid-water above the deeper bommie sections, and scorpionfish rest in camouflage on the bommie faces throughout the depth range.

FAQs
Sea turtle sightings at Aquarium are among the most reliable of any Havelock dive site. They are not occasional visitors but regular, predictable residents of the site. The seagrass patches in the sandy sections between bommies provide feeding ground, shelter, and orientation. Green turtles and hawksbill turtles are both present.
A bommie is a coral pinnacle, an individual coral formation rising from a sandy bottom, isolated from the surrounding reef rather than forming part of a continuous wall or slope. Aquarium is built on scattered bommies of varying sizes at varying depths, each a self-contained ecological unit with its own coral community, its own resident fish, and its own crevice life.
Aquarium is specifically recommended for nervous first-timers due to its shallow depth (2-15 metres), bright water (natural light from surface to bottom), clear water (visibility 15-20 metres), and densely populated reef fish species. The water column is bright, not dark — you can see the surface above you and the sandy bottom below you simultaneously. You're surrounded by colourful, non-threatening life from the start, with your instructor beside you throughout, making it one of the safest and most pleasant dive experiences.
Certified divers (Open Water or above) pay INR 3,500 + 18% GST per person. Non-certified divers and non-swimmers pay INR 6,500 + 18% GST per person.
