Solubility Question

What's the solubility of inorganic fluorides? I'm guessing it's not considering I got this question wrong..but is it soluble with things besides the alkali metals?

I'm under the impression that fluorides are generally not very soluble due to the significant decrease in entropy of water due to solvation of the fluoride.

Assume soluble; use the cation rules to predict ( e.g NH4F will be soluble)
You wont see a question like BaF2 solubility; there are some trends in inorganic chemistry but there are always exceptions. If you pay attention, you will see that the general chemistry textbooks dont say much about the solubility of fluorides. The reason is the unpredictable behavior of fluorides. But, assume solubility if otherwise was stated.

Topscore said it isn't soluble in solution :-\
