Lymphocystis in Indian Glassfish Chanda ranga Imported from Thailand to Puerto Rico

Lymphocystis occurred in Indian glassfish Chanda ranga imported to Puerto Rico from Thailand. This is only the second report of lymphocystis in Indian glassfish and in the family Chandidae (or Ambassidae), but the disease appears to have become widespread in this species in the ornamental aquarium fish trade throughout the southeastern USA and the Caribbean. We report the first occurrence of Indian glassfish with lymphocystis in a region where the fish can survive in the wild. Lymphocystis is not known in Puerto Rican fresh‐water fishes, and the introduction of this disease should be avoided.
