Austrolebias reicherti

Austrolebias reicherti (Paso del Dragon, 2020)

Returning fish to the shed now that cold weather approaches, this trio of Austrolebias reicherti (Paso del Dragon) appears. They are about eight months old. For a while, I had a line from the same location where the males had a more pronounced blue hue. We managed to karyotype one of them and it turned out to be a triploid. Whether that was the cause of the colour difference we observed or not could be answered by karyotyping a bunch of wild-caught fish with colour differences. Karyotyping can be done by fin-clipping and a recapture where the regenerating fin is sampled, no fish would have to be sacrificed for this test.
