Three perciform species associated to coral reefs were, for the first time, investigated under a cytogenetic focus : Holacanthus ciliaris and H. tricolor from family Pomacanthidae and Chaetodon striatus from family Chaetodontidae. Individuals were collected at different sites along Atlantic coast of Brazil. All of them showed similar chromosomal features, considered primitive for the order. These characteristics are 2n=48, NF=48, NORs located at interstitial position on long arms of a single chromosomal pair and discrete heterochromatic blocks at centromeres and NORs.
