I was looking at the different Coius.
I noticed the difference in the pictures, then read the description of the different speices.
I thought I had a Coius microlepis but it looks more like a Coius undecimradiatus.

Coius microlepis
Has the deepest body of any species of Coius, 2.1-2.4 times in SL. Specimens from mainland Southeast Asia invariably with five full bars, specimens from Borneo with 6-7 bars, all usually continued across ventral surface of body. First bar extending uninterrupted and undiminished across opercle and onto thoracic region, and continued across ventral surface of body; a well defined black mark on ventral surface of body immediately anterior to base of pelvic fins (not present in other Coius). Partial bars almost invariably absent. Branched dorsal rays 14-18; branched anal rays 9-11, usually 10

Coius undecimradiatus
Dorsal spines (total): 12-12; Dorsal soft rays (total): 16-19; Anal spines: 3-3; Anal soft rays: 10-11. Body depth 2.1-2.4 times in SL; relatively narrow vertical bars, the first bar usually not continued onto thorax or across ventral surface of body and the second bar originating at the base of 5th to 6th dorsal-fin spine; usually 11 branched anal-fin rays (Ref. 27732); about 17 scale rows between upper part of lateral line and dorsal base
