FBname: Rubyspot cardinalfish
Comments: Inhabit coral reef (Ref. 75154).  Form small aggregations (Ref. 33415).  Distinguished from  <i>A. cyanosoma</i> by the presence of a single red spot at the midbase of the caudal fin, a higher number of gill rakers, and apparently a smaller maximum size (Ref. 33415).
