RHi there
Never kept these fish before, but I've done plenty of reading - you can do similar: just type in "electric eel" or "Electrophorus electricus".
They get pretty large, and can be quite 'fragile' at first too, so make sure you're well prepared in advance with both a large tank and plenty of knowledge. And no, the water shouldn't shock you unless the electric eel has a reason to feel threatened.
PS: Don''t try grab it.
Regards
