Assiculus is a genus of fish in the "dottyback" family Pseudochromidae. It is monotypic, containing only Assiculus punctatus. It is a small species of dottyback which is covered in small, bright blue spots. The males are bluish in colour while the females are greenish-yellow and are smaller than the males. "A. punctatus" is found in coastal areas in the vicinity of reefs and weedy areas; normally in rather turbid waters as deep as . This secretive species frequents areas where there are highly eroded limestone reefs and rocks. 
The genus and species were first published by Sir John Richardson in an appendix to Volume 1 of John Lort Stokes' 1846 "Discoveries in Australia". The specific name "punctatus" references the small blue spots on the dorsal part of the body and fins.
