Etymology: Manonichthys: Name is a combination of Greek manon which is a kind of sponge, and ichthys for fish, referring to the sponge-dwelling behaviour of the species under this genus.; jamali: Named for a hardworking crew member of M.V. CITRA PELANGI diving vessel, Jamal,.

Morphology | Morphometrics
soft rays: 15 - 16. This species is distinct from its congeners in having the following features: pectoral fins hyaline; at least some ctenoid cheek and opercular scales; caudal-fin is rounded to truncate in young fish to strongly emarginate or lunate in adults; predorsal scales 17-22, extending anteriorly to point ranging from slightly posterior to slightly anterior to PIO pores; presence of a prominent dark bar across anterior caudal peduncle and adjacent posterior body extending onto basal 1/2 of posterior dorsal and anal fin rays (Ref. 74994).
Inhabits frequently dense thickets of staghorn Acropora corals, encrusting layers of Galaxea corals, or rocky debris at depths of about 9-16 m. Either encountered solitarily or in loose groups of 2-4 individuals that range over an area of about 1.5-2 m. Observed to occasionally enter sponges of the genus Callyspongia. Its color pattern and behavior indicate a mimetic relationship with the common damselfish Chromis retrofasciata with which it co-occurs (Ref. 74994).
