Etymology: Meiacanthus: Greek, meion = less = lessen + Greek, akantha = thorn (Ref. 45335); tongaensis: Specific epithet refers to Tonga Is., where it appears to be endemic.
Environment: milieu / climate zone / depth range / distribution range
Marine; pelagic-neritic; depth range 0 - 16 m (Ref. 7401). Tropical
Pacific Ocean: apparently endemic to Tonga.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 10.0 cm SL male/unsexed; (Ref. 54980)
soft rays: 17 - 18. Lunate caudal fin with elongated lobes in adults; yellowish green on head and dorsally on body, shading to light yellow ventrally; greenish yellow dorsal and anal fins, broad black stripe near dorsal fin base; caudal fin base and lobes greenish yellow with centroposterior part transparent with pale greenish yellow rays. Segmented caudal rays 11-12 (usually 11); lateral line terminating below 3rd to 7th dorsal soft rays (Ref. 54980).
Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).
