I would be very suspicious about fish or invertebrates in petshops
explicitly named 'freshwater'. Indeed it is amazing how they come up with
those names. In the vast majority of these cases, those 'f/w' animals
are just brackish or even marine, anadromous at best.
If they are in a shop that can't tell an eel from a snake they are
definitely not freshwater I think. These are the kind of shops who invent
those stupid names.
I know some real sharks are anadromous, and can stay up river for a long
time, such as the Zambezi shark. I don't know of a true f/w moray eel
exists. Can you share those scientific names Mach?
