One after fish bones (5)

I believe the answer is:

carpi

'bones' is the definition.
(I've seen this before)

'one after fish' is the wordplay.
'one' becomes 'i' (Roman numeral).
'after' is a charade indicator (letters next to each other).
'fish' becomes 'carp' (carp is a kind of fish**).
'i' after 'carp' is 'CARPI'.

(Another definition for carpi that I've seen is " Wrist bones - Capri (anag)".)

I've seen this clue in The Times.
