Matilebias juanlangi: a wild-line annual killifish from the wetlands of Uruguay.
Wild-descended F1 pair (first generation bred from wild-caught parents), collected at Paso De La Cruz, Uruguay.
A seasonal annual endemic to Uruguay's Neotropical wetlands, where its shallow pampa pools dry out each year. Its wild habitat is shrinking fast, which makes captive-bred fish like these valuable.
Care: Annual species. Spawns in peat, eggs incubate 1 to 2 months.
