In this study, we used the next-generation sequencing method to deduce two complete mitogenomes of Cocos lemonpeel angelfish (Centropyge flavissima) and Eibl's angelfish (Centropyge eibli) for the first time. The assembled mitogenome, consisting of 17 010 bp and 17 101 bp, showing 98.3% identity each other. Both mitogenomes follow the typical vertebrate arrangement, including 13 protein coding genes, 22 transfer RNAs, two ribosomal RNA genes, and a non-coding control region of D-loop. D-loop contains 1302 bp in C. flavissima and 1392 bp in C. eibli and locates between tRNA-Pro and tRNA-Phe. The overall GC content is 45.2% for C. flavissima and 44.9% for C. eibli. Complete mitogenomes of C. flavissima and C. eibli provide essential and important DNA molecular data for phylogenetic and evolutionary analysis for marine angelfishes.

Hybridisation and introgression of eukaryotic genomes can generate new species or subsume existing ones, with direct and indirect consequences for biodiversity. An understudied component of these evolutionary forces is their potentially rapid effect on host gut microbiomes, and whether these pliable microcosms may serve as early biological indicators of speciation. We address this hypothesis in a field study of angelfishes (genus Centropyge), which have one of the highest prevalence of hybridisation within coral reef fish.

In vertebrates, anti-Mullerian hormone (Amh) secreted by Sertoli cells (SC) performs a pivotal function in male sex differentiation. Compared with that of higher vertebrates, the expression pattern of Amh is more diversified in fish. In this study, the full-length complementary DNA (cDNA) of Amh in Centropyge vrolikii (Cv-Amh) was cloned and analysed, which was 2,470 bp, including a 238 bp 5'UTR, a 1,602 bp ORF and a 633 bp 3'UTR; the similarity of Amh between Cv-Amh and other fish is relatively high.

As a member of the Sox gene family, Sox3 plays a vital role in gonadal development and gametogenesis. Nevertheless, the exact expression pattern of this gene in fish is still unknown. Here, we identified the Sox3 gene of Centropyge vrolikii, namely, Cv-Sox3.

The homeodomain transcription factor Nanog plays a crucial role in the embryonic and gonadal development and the maintenance of embryonic stem cells (ESCs), interacting with transcription factors such as Oct4 and Sox2 in mammals. Nevertheless, its pathways to molecular mechanisms remain unclear as to teleosts. This study investigates the role of the Nanog gene in gonadal development and sex reversal of pearlscale angelfish (Centropyge vrolikii).

The Bicolor Angelfish, , is a tropical coral reef fish. It is named for its striking two-color body. However, a lack of high-quality genomic data means little is known about the genome of this species.
