背棘 (總數) : 13 - 19; 背的軟條 (總數) : 53; 臀鰭軟條: 49; 脊椎骨: 75. Distinguishable by its dorsal spine count of 13-19 and a series of 3-6 conspicuous ocelli along the base of the soft dorsal fin (Ref. 27732). The ocelli along the base of the dorsal fin are much larger than those in M. aral and the dorsal and caudal fins lack the fine striations seen in M. aral and M. meklongensis (Ref. 39392). Dorsal, caudal and anal fins not fused (Ref. 43281).
可區別的用它 13-19 與一系列的 3-6個顯著的假眼斑的背棘計數沿著軟背鰭的基底.(參考文獻 27732) 假眼斑沿著背鰭基底是比那些在 M. aral 大很多，而且背鰭與尾鰭缺乏被在 M. aral 與 M. meklongensis 中見到的細紋.(參考文獻 39392) 背鰭、尾鰭與臀鰭不融合了。 (參考文獻 43281)
Found at bottom depths in slow-moving or standing waters. Often lies buried in the silt, sand, or fine gravel with only a portion of its head protruding from the bottom (Ref. 12693). Enters flooded forest (Ref. 9497). Emerges at dusk to forage for food. Feeds on benthic insect larvae, crustaceans, and worms (Ref. 12693). Marketed fresh and often seen in the aquarium trade (Ref. 12693).
在緩慢移動的或不流動的水域中發現在深底部了。 時常躺臥埋藏在淤泥，沙子或細砂礫之中只有從底部凸出的它的頭部的部分.(參考文獻 12693) 進入被水淹沒的森林。 (參考文獻 9497) 在薄暮浮現覓食。 吃底棲的昆蟲幼生，甲殼動物，與蠕蟲。 (參考文獻 12693) 在市場上銷售生鮮地了而且時常在水族貿易中見到.(參考文獻 12693)
