Frostfin Cardinalfish (Ostorhinchus hoevenii) ミヤコイシモチ
The Frostfin Cardinalfish is yellow brown. Black membrane between spines at the tip of the spinous dorsal fin, followed by a white margin.
From the top of the Frostfin Cardinalfish you can see the white spots and their locations on the dorsal side. This fish seems to be also called Ostorhinchus ishigakiensis which was originaly known as Apogon ishigakiensis. Some descriptions match some don’t. If I ever find out which is correct, I will update this.
