Fish selected from little else (4)

I believe the answer is:

eels

'fish' is the definition.
(eel is a type of fish)

'selected from little else' is the wordplay.
'selected from' indicates a hidden word.
'EELS' is hidden in the letters of 'little else'.

(Other definitions for eels that I've seen before include "(Slippery) fish" , "Water snakes twisting in lees" , "Slippery customers" , "Jellied --, traditional dish" , "Elongated fish" .)

I've seen this clue in the Evening Standard.
