We loved this place , spent 4 hours just mesmerised by some of the exhibits...especially the Nile Crocodiles and huge fish in the main tank......well worth the money

Huge fishes that look more like old gods than your run-of-the-mill stuff you find at the fish market.

Took my 5 year old there to get a break from the heat and "shopping". Absolutely loved the aquarium - the english commentary/explanations are a little brief but loads of animals to see. Plenty of other activities too to keep kids engaged. Parking is easy nearby or you can take the bus.

This aquarium is divided in to five zones on five continents, Nile, Murray-Darling, Mekong, Amazon and Ebro. The signage is informative and the fish, mammals and birds look well cared for. The aquarium is on two floors and is well laid out. There is a good film about the birth of the baby Nile crocodiles born here. Well worth a couple of hours visiting.

Compared with our benchmark :- Sydney Aquarium, this aquarium is on par if not better in many ways. The focus is freshwater fish habitats and they do this really well! There were also animals such Marmots (monkey from the Amazon) iguanas, snakes, monitors and many different types of turtles. The kids absolutely loved it. I do not understand why it was not crowded when we visited. The whole area it resides in was built for world expo 2008 and the whole place is now devoid of people, this may be part of the reason. We had visited San Sebastian aquarium last week and this aquarium is much bigger and more interesting.

You can get a combined ticket for the aquarium and the Zaragoza tourist bus from the tourist office at the station for only 15€ - a bargain! The aquarium was huge and really well laid out and presented! The focus on the five different rivers really showed the contrast in environments in different parts of the world. Strongly recommended during a visit to Zaragoza.

Good way to spend a couple of hours. It was much larger than we expected, with a very well layer out route & all the information was in three languages ( Spanish, French & English)

After a long walk along the river we made it to the aquarium. It was a fun way to spend a few hours. They also have a beautiful terrace upstairs with great views.

A walk from the old town and we found it easily amongst the mainly empty Expo site. It was feeding time for many and we were invited to watch and have explained several details about some of the animals there on a quiet Monday lunchtime.

I have never visited such a splendid aquarium and very much surprised by the types and sizes of fish and other creatures. A very worthwhile visit.

Well worth the trip to see this. Easy to get to using the hop on hop off tourist bus which is valid for 24 hours. The aquarium is the largest fresh water aquarium in Europe. Kids and adults will enjoy this alike

The Aquarium is on the site of Expo 2008 and is not well sign posted. The hop on hop off bus stops there. There is a good selection of exhibits with a few mammals as well as fish and reptiles but the descriptive panels by the tanks are quite confusing since some of them dissolve into a different language every few minutes.

This aquarium was absolutely amazing as it had animals from different rivers rather than seas. It showed a different aspect of aquariums and animals and therefore was interesting and entertaining. I absolutely loved it!

Totally diferent from a sea/ ocean acuarium. We had never visited a fluvial ( rivers) acuarium before. Great experience.

It's a bit pricey at $16 euro but it is quite a nice older style aquarium that is well worth a visit. The arapaima exhibit is amazing. My wife and I went and had the place to ourselves. Loved it.
