A fish of the electric type? (3)

I believe the answer is:

eel

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

'of the electric type?' is the wordplay.
'of' indicates the answer is hidden within the clue.
'EEL' can be found hidden inside 'the electric type'.

(Other definitions for eel that I've seen before include "Slippery creature" , "A sea snake" , "Slender fish" , "Almost scaleless fish" , "Moray or electric, for instance" .)

I've seen this clue in the Evening Standard.
