The small fish eaten fried with peanuts are called teri in Indonesian. Kamus Besar Bahasa Indonesia defines teri as "A very small edible sea fish classified into the genus Stolephorus".

Googling teri and stolephorus led me to this site:

http://makeashorterlink.com/?P333514C, which gives different names for the fish in different languages. The home page for the site, which seems to be devoted to ichthyological nomenclature in different languages is http://www.fishbase.org/search.cfm.

The dish is called teri kacang, googling which will lead you to recipes for those so inclined.
