Am I going mad or can you put anchovies into a beef chilli?

I have a chilli already simmering on the stove but just came across a tin of anchovies and I seem to remember somewhere reading that it can add richness to the flavour - am I right or am I going bonkers? Don't really want a fishy chilli?

I always add them to bolognese, but have never put them in a chilli.
