alcina, are you using full time auto focus? If so you may want to try using the shutter half way down method instead. IMHO I think it works better underwater.
I'm from being any expert on Photoshop but you can also try using the lasso tool and capture only the fish with it then use the unsharp mask on it separately from the rest of the photo if it looks like you are over-sharpening the entire photo.
