Monophyly of the Agoniatinae (Characiformes: Characidae)
Zootaxa, 2013The Characidae is the most diverse family of Neotropical fishes, currently encompassing more than one thousand valid spe-cies. Some subgroups within this family still lack phylogenetic definitions, being diagnosed on the basis of combination of characters, a common procedure in pre-cladistic studies. Agoniatinae, currently composed by two valid species,

Endocardiosis in Tetras (Family Characiformes)
Journal of Comparative Pathology, 2019Proliferative, myxomatous change was identified in the cardiac valves (i.e. valvular endocardiosis) with extension into some cardiac walls (i.e. mural endocardiosis) of five tetras (four neon tetras [Paracheirodon innesi] and one rummynose tetra [Hemigrammus rhodostomus]).
