The tambaqui is a species of freshwater fish native to the Amazon and Orinoco basins, not originally endemic to this specific coastal region of Sergipe.
The fish in the lagoon can reach significant sizes, often exceeding 50 centimeters in length.
The water clarity is maintained by the natural groundwater springs that feed the lagoon basin.
The interaction between humans and the fish is strictly managed by local operators to prevent overfeeding or distress to the wildlife.
The lagoon is situated within a transitional landscape between the Atlantic Forest remnants and the coastal dunes.
Lagoa dos Tambaquis is a freshwater lagoon located in the municipality of Estância, Sergipe, famous for the large, docile tambaqui fish that inhabit the clear, dark waters. The lagoon features a structured tourist complex with floating decks, restaurants, and recreational areas designed for swimming and interaction with the aquatic life. Visitors can swim alongside the fish, which are accustomed to human presence due to regular feeding. The lagoon is part of the Lagoa Redonda ecosystem, fed by natural springs. The water is characteristically transparent, allowing for high visibility of the fish and sandy bottom. It serves as a primary day-trip destination from the state capital, Aracaju. The site is managed as a commercial recreation area with infrastructure providing amenities for families and swimmers.
The floating decks offer the best perspective for underwater photos or shots capturing the fish swimming around legs.
Bring a snorkel mask to observe the fish clearly underwater, as the sandy bottom and dark water create unique visibility.
Visit on a weekday to avoid the high volume of tour buses that arrive on weekends and holidays.
Apply biodegradable sunscreen to protect the water quality of the lagoon ecosystem.
Do not attempt to catch or harass the fish; avoid visiting during peak weekend hours if you prefer a quiet experience.
Avoid using chemical-based insect repellents or sunscreens while entering the water; refrain from feeding the fish anything other than provided, approved food.
