Demersal
Sea catfishes are extremely difficult to ID as most of them look identical. It is ID mainly thru the different shapes of 'upper tooth patches' in its mouth & partially from the different patterns on the 'top view of the head.'
Dorsal spines:1, rays:7 ; Anal spines:1, rays:12
*Take note that there's a layer of yellow slimy coat on its body when it is alive [refer to small pic above]
Credit goes to 'Kelvin KP Lim' in helping in the ID of this fish
