Crossword Genius

Unusual hoarder of fish eggs (4,3)

Ross

I believe the answer is:

hard roe

'fish eggs' is the definition.
('hard roe' can be a synonym of 'fish eggs')

'unusual hoarder' is the wordplay.
'unusual' indicates an anagram.
'hoarder' is an anagram of 'HARD ROE'.

'of' is the link.

I've seen this clue in The Telegraph and The Guardian.
