A yellowish-orange basslet with a pale-edged red stripe from the rear of the gill cover to the tail base, and a purple-edged stripe from the snout to the pectoral-fin base. Juveniles lack the red stripe.
Redstripe Basslets live in harems with a male guarding many females. All individuals begin life as females, and some change sex from female to male during their life cycle. If the male dies or disappears, the dominant female will change sex to replace the missing male.
