Spur-cheek Cardinalfish (Pristiapogon fraenatus) ヒトスジイシモチ also Spinyeye (size 11cm)
Spur-cheek Cardinalfish are found hiking in caves in the daytime. They come out at night to hunt smaller things. Amami 2025
Another Spur-cheek Cardinalfish next to a cleaner shrimp. I am not sure where their spur is. I am guessing at the back of the gill plate. Amami 2025
