Suspect your letter A in 14d is wrong. Try anagram of 'a wee fish', but without the 'h' - Almost an anagram...
12a Wee fish(6) - I have the leters and spaces which you have. Keep having the urge to write 'weegie' in there, but that is the wrong answer, and rude as well. Comes from being a nasty wee east coaster..if anyone can help with the wee fish, please do, and my email will pick it up
