Fish and game (8)
I believe the answer is:
sardines
I believe this clue is a double definition.
'fish' is the first definition.
(I've seen this before)
'game' is the second definition.
(sardines is a hiding game)
'and' is the link.
(Other definitions for sardines that I've seen before include "Cumulative hiding game" , "Squash-together party game" , "Children's game - fish" , "Small fish, usually canned" , "Young pilchards" .)
