A loop audio tape of tidal wash envelops Prague’s little known aquarium, Mořský Svět. The suspended manta ray may be huge, but the tanks are small although well stocked with tropical and fresh water fish. One tank has, we presume in honour of Finding Nemo, clown fish and a tang. Deadly but beautiful scorpion and turkey fish languish looking like fully sailed galleons, and soft corals billow in the current. It’s not huge, but makes an interesting detour. Signs are Czech only.
