Fishes in the sunshine? (4)
I believe the answer is:
rays
'the sunshine?' is the definition.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for rays that I've seen before include "shafts" , "Flat fish" , "Columns of light or heat" , "Single lines of light" , "Fish with wing-shaped fins and long tails" .)
