The morphological and biophysical characteristics were determined for a previously unreported angelfish reovirus isolated from a moribund angelfish Pomacanthus semicirculatus exhibiting clinical signs associated with head and lateral line erosion syndrome. Viral particles were nonenveloped, possessed a segmented double‐stranded RNA genome enclosed by a double nucleocapsid, and were resistant to inactivation by ether and low pH. Electrophoretic and serologic characteristics of this viral agent were compared with those of other aquatic reoviruses isolated from different fish hosts (chum salmon Oncorhynchus keta , golden shiner Notemigonus crysoleucas , and channel catfish Ictalurus punctatus ). Based upon these findings, molecular weights were estimated for the 11 genomic segments (0.34–2.4 × 10 6 ) and some of the major structural viral polypeptides (34.4–137.0 × 10 3 ).
