The complete mitochondrial genome of Trichogaster microlepis was determined in this study. It is 16,435 bp in size and consists of 2 rRNA genes, 13 protein-coding genes, 22 tRNA genes and a non-coding control region (D-loop). The overall base composition of the heavy strand of the T. microlepis mitochondrial genome is A: 29.50%, T: 28.38%, C: 26.62%, and G: 15.49%. The total length of the 13 protein-coding genes was 11,427 bp. This study provides an important data set for the phylogenetic and taxonomic analyses of the Trichogaster species.
