Description The results of the Cytogenetic studies carried out in two marine ornamental fishes, Chaetodon rollare and
Stegastes insularis, occurring in the south-eastem Arabian Sea, by Giemsa staining and nuckolar organizer
regions (Ag-NOR) staining are reported. The diploid chromosome number (2n) in C. collare and S. insularis
was found to be 48. Based on the karyomorphology, the karyotype formula was derived as 48t (FN=48) and
14m + 24 sm + 6st + 4 t (FN=86), respectively for these two species. Silver staining revealed presence of one
pair of NORs in both the species. This is the first description of karyotypes in these species using conventional staining and chromosome banding techniques.
