Through a Groupon promotion, I went to for a day's visit to the Aquatopia. The web site looks great - 10,000 fish to be explored. Unfortunately, after about 1 hour I had seen everything and read every information display in the aquarium.
The place is small. The map lists about a dozen themed rooms, the rooms however are quite small, and contain only very few displays. In most of them, I saw the fish spinning around quite stressed, often the aquariums were only 20-30 cm wide. Two of the theme "rooms" are actually the escalators: Decorated with a shark's mockup, it suddenly becomes a major item on the floor plan. I think there were probably more like 250 fish there, instead of the 10,000 advertised in the brochure.
In hindsight, I regret going there - 14 Euros was certainly not worth it. I had been to the Blijdorp zoo in Rotterdam, the aquarium is quite stunning there. In summary, save your money and time and go somewhere else.
