Review of 27 Fish Flavor-CSL:

This had the spot on flavor you're trying to achieve. The issue for me was this is a harsh flavor.  Added marshmallow to try to soften it to no avail. Even adding smooth(ethyl maltol) did absolutely nothing to tame the harshness. As much as I want a candy fish, I can't use this until I can figure out how to smooth it out without muting the flavor.
