Display a river fish (5)

I believe the answer is:

array

'display' is the definition.
('array' can be a synonym of 'display')

'a river fish' is the wordplay.
'river' becomes 'r'.
'fish' becomes 'ray' (ray is a kind of fish).
'a'+'r'+'ray'='ARRAY'

(Other definitions for array that I've seen before include "Impressive display; matrix" , "Imposing show or military order" , "Rig up" , "Impressive exhibition" , "Matrix; elaborate clothing" .)

I've seen this clue in The Telegraph.
