yes it is true. there are very few true freshwater species in the world.
most live in estuaries but because they occasionally migrate upstream and have were caught by Victorian scientist in that freshwater they were labelled as freshwater fish.
as we became more knowledgeable about these fish and started to understand their habits we realised they were actually brackish that occasionally venture into freshwater, probably in search of food or even to mate.
