Just a bit of cyano...

I advise against this. I don't think any crustacean, echinoderm or gastropod (aside from perhaps a few species of conch, Strombus spp.) has been shown to eat cyano, and I know none of the ones I had in my tank did. Nudibranchs are a bad choice for any tank (except perhaps in the case of Tridachia crispata or Berghia verrucicornis which eat hair algae and Aiptasia spp. anemones, respectively). Therefore I am of the opinion that this is a waste of money, effort and in some cases animal life. More importantly, I feel it is more important to look for solutions to problems in a tank, rather than just their symptoms.

And of course, as noted, cyano and many other common algael/bacterial pests are part of the natural maturation process of the tank and will likely diminish in time, and aren't worth worrying too much about unless they are beginning to affect the health of your other livestock.
