Old Wife
Most fish have several common names and Old Wives are no exception - they're also known as Angelfish, Moonlighter, Zebrafish and our personal favourite Bastard Dory.
Although Zebrafish is the obvious choice of name for these fish due to their distinct pattern, most people refer to them as Old Wives. They got this name because, when caught by fishermen, they complain by making a noise like chattering old wives - who can blame them?
