Some superior feed for pond fish (4)
I believe the answer is:
'pond fish' is the definition.
'orfe' can be an answer for 'fish' (I've seen this before). I'm not certain of the 'pond' bit.
'some superior feed for' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'ORFE' can be found hidden inside 'superior feed for'.
Can you help me to learn more?
(Other definitions for orfe that I've seen before include "swimmer" , "Silvery freshwater fish of carp family" , "Fish of carp family; rhymes with quayside" .)
