Short description সনাক্তকারী নির্দেশক | বহিঃ অঙ্গ সংস্থান | মরফোমেট্রিক্স

পৃষ্ঠীয় কাঁটা (মোট ) : 8; পৃষ্ঠীয় নরম পাখনা দন্ড (মোট ) : 12 - 13; পায়ূ কাঁটা : 3; পায়ূর নরম পাখনা্তুন্ড: 10 - 11. Body elongate; 3 primary color phases, the smallest with a black mid-lateral stripe which continues as pale red blotches on head; back above stripe yellow on reef fish and whitish on fish from inshore non-reef areas, and body below white. The largest phase, has a bright blue head and a green body with two broad vertical black bars anteriorly which are separated by a light blue interspace; this phase is always male. The small yellow phase with the black stripe may be either male or female (Ref. 13442).

জীববিজ্ঞান     শব্দকোষ (উদাহরণ স্বরূপ epibenthic)

Inhabits reef areas, inshore bays and seagrass beds. Feeds mainly on zooplankton and small benthic animals, but may also feed on ectoparasites of other fishes (Ref. 9626). Spawn at midday throughout the year (Ref. 26938). A protogynous hermaphrodite (Ref. 55367). Generally of no interest to fisheries because of its small average size (Ref. 5217).

Life cycle and mating behavior Maturities | প্রজনন | Spawnings | Egg(s) | Fecundities | শুককীট

A diandric species (Ref. 55367). Sex reversal is completed in more than 3-4 weeks (Ref. 34185, 34257). Length at sex change = 8.3 cm TL, forms leks during breeding (Ref. 55367).
