The public aquarium has 41 tanks including reptiles, insects and amphibians, amongst others, Mediterranean fish, including fish commonly found in Maltese waters together with replicas of historical artefacts that one can find in the seas around the Maltese islands.
The main tank of the aquarium houses species from the Indian Ocean, including eight black tip sharks, horn sharks, rays, eels and other exotic species. The main tank is approximately 12 meters in diameter and has a walk-through tunnel that allows visitors to experience the fish at a much closer range.
All tanks are expertly themed to replicate the underwater environment. Additional features of the public aquarium include a class room facility, interpretation, touch pools, a temporary exhibition space, veterinary and quarantine facilities, etc.
