@Mr Gharial The mudskippers are kept together with the banded archerfish in the aquarium building. They are in the large aquarium at the entrance to the building. During my visit, I did not know Ouwehands had them either. They were also not signed (like almost all species in the aquarium building at that time). But when I looked a bit longer I suddenly saw something moving on the 'beach' of the aquarium.
