Species profiles
Explore our visual directory of rare and endangered livebearing fishes curated at our research facility in Vodňany. From iconic Mexican goodeids to specialised livebearers, each profile offers an overview of morphology, heritage, and conservation significance for researchers and dedicated aquarists alike.
Ameca splendens and Zoogoneticus tequila
Known respectively as the butterfly goodeid and the tequila splitfin, these species represent crucial conservation cornerstones. Ameca splendens is celebrated for its distinctive caudal yellow band and active demeanor, while Zoogoneticus tequila-once critically endangered in its native Jalisco basin-stands as an international triumph of cooperative ex-situ breeding programs and structured reintroduction efforts.
Xenotoca doadrioi and Skiffia multipunctata
Xenotoca doadrioi (the San Marcos redtail splitfin) captivates with iridescent body scales and intense dorsal and caudal coloration in dominant males. In contrast, Skiffia multipunctata (the spotted skiffia) exhibits intricate patterns and refined courtship dynamics. Both species highlight the extraordinary evolutionary diversity found within the upland waters of central Mexico.
Heterandria formosa and Dermogenys pusilla
In addition to goodeids, our stock center maintains other vital viviparous lineages. Heterandria formosa (the least killifish) is one of the world's smallest vertebrates, known for superfetation where females nourish multiple broods at various developmental stages. Alongside it, Dermogenys pusilla (the wrestling halfbeak) provides research insights into surface-dwelling adaptation and specialized viviparous biology.
