Maretarium houses a number of smallish and one larger fish tank with local fish species. The displays are not especially spectacular and some species dominate. The entrance is costly.

Dull exposition, relatively expansive... Nothing to do there for more than 20min. Very disappointing actually. During fish feeding no translation available.
