Forgive me for pointing this out, but, a picture is worth a thousand words, and some words paint a picture. No matter how cleverly your logo may be designed, no one is going to relate painting and drywall with FISH. Despite your best intentions, I would seriously rethink using F.I.S.H. as an anchor for your painting business. This is how I would communicate with any of my clients when I see a serious issue with their proposed identity. I hope you understand my view and take it in the spirit in which it was offered.

I appreciate your input, but FISH is an acronym used to describe what our company is about .....It is not "literally" a fish......The acronym is:
F-aith I-ntegrity S-ervice H-eart
Our company is a service of painting and drywall founded on the Christian values of faith, integrity and sincerity(heart) In the past, and still at times in the present the symbol of a fish was/is used to designate who was/is a believer in Christ and who wasn't/isn't. (perhaps you've seen then on the backs of some cars?) For these reasons, we feel the name is "catchy" and easy to remember. It states simply who we are (Christians) who do painting and drywall.
Thanks again for your input and a chance to better explain "the name"

Thank you for considering my input and replying in kind. I do appreciate you taking the time to explain the basis of your identity, but the fact that you have to explain it further proves my point. I specialize in outdoor advertising and vehicle graphics. Your identity musty be clearly stated and be absorbed in a matter of seconds. Your business identity does not have the luxury of having to explain it's meaning to every passerby.

I believe I can sum up the issue very clearly for you, and I mean no disrespect whatsoever.
Would you not be puzzled by a fish market with a sign that read P.A.I.N.T.?
I do wish you the best of luck - and it will be a better designer than I that may help make this for you.
I do look forward to seeing what someone comes up with.
I hope I was helpful to you in some way.
