Fishy fellow? (3)
I believe the answer is:
ray
I believe this is a double definition.
'fishy' is the first definition.
(type of fish)
'fellow?' is the second definition.
(man's name)
(Other definitions for ray that I've seen before include "Pencil of light" , "Beam of light or flat fish" , "Gleam" , "may be electric" , "Man, maybe" .)
