Also known as Blackspot Threadfin, Slender Five-finger Threadfin, Small-mouthed Threadfin, Striped Threadfin, Tasselfish, Threadfish

Description

Also known as Blackspot Threadfin, Slender Five-finger Threadfin, Small-mouthed Threadfin, Striped Threadfin, Tasselfish, Threadfish.

Found singly or in small schools in murky churned waters of coastal estuaries, mangrove creeks and rivers.
They feed on small crustaceans, fish and benthic organic matter.
These fish have extended rays on their Pectoral fins which act like fingers which they use for scouring the sand/mud bottoms for food.
Length - 25cm
Depth - 2-55m
Widespread Eastern Indian Ocean, Western Pacific

Because Threadfins stir up the sand with their extended rays they are often followed by other fish to share in their scraps, also being a schooling fish they are popular with anglers. Ref: https://www.fishbase.in/summary/Polydactylus-microstomus.html
