Fishes present an exceptional level of diversification among vertebrates, whose adaptive
instructions contained in their genome are physically organised in their chromosomes …

The genus Tetranematichthys has only three species, and none of them have undergone
cytogenetic analyses. Therefore, this study brings for the first time the analysis of …

Lebiasinidae is a small fish family composed by miniature to small-sized fishes with few
