What I see on 5 & 6.
Ocular flap structure is RES like not BG.
Face mottling is RES
Fins are CNBG - see light edge on pelvic fins
Lateral line structure (body shape is CNBG)
Nose (just above eye structure or where the helmet starts)see the double line of scales (2 with about 1/2 inch between) where the copper bar goes - this is classic CNBG.
