Where one may find flounders floundering? (2,3)
I believe the answer is:
at sea
'floundering' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for at sea that I've seen before include "floundering" , "The men in the dock are not" , "stumped" , "On a moving ship?" , "Sailing on a ship?" .)
