Hi Mart,
Chitons are grazers which eat mostly algae (including corraline alga in some cases). I am not too sure if they also graze on corals or not so I would suggest that you either leave it in your display tank and keep a very close eye on it or just move it into your sump.
Have a look at a book called "Two Oceans - A guide to the marine life of South Africa". It is a good general guide to the more common marine life that you would come across along our coast.
