Snake cleaner fed, nervously (3,2,5)

I believe the answer is:

fer-de-lance

'snake' is the definition.
(fer-de-lance is a kind of snake)

'cleaner fed nervously' is the wordplay.
'nervously' indicates an anagram.
'cleaner'+'fed'='cleanerfed'
'cleanerfed' anagrammed gives 'FER-DE-LANCE'.

(Another definition for fer-de-lance that I've seen is " Venomous American snake".)

I've seen this clue in The Telegraph.
