General Description
The Charco Palma Pupfish, scientifically known as Cyprinodon Veronicae, can be identified by its short maxilla, diffused dark bars along the sides of males, and an irregular ocellus on the dorsal fin of females. The species lacks teeth on the 4th ceratobranchial and exhibits violaceous blue coloring in nuptial males.
Aquarium Setup
The Charco Palma Pupfish requires a minimum tank size of 60 liters with a setup that offers multiple hiding spots for broken lines-of-sight. Adequate cover through aquatic plants and wool mops is recommended. Filtration should be air-powered with sponge-type units to avoid harming eggs or fry. While lighting is not essential, it can be used optionally, and the growth of filamentous algae is encouraged.
Behaviour
These toothcarps are known to exhibit territorial behavior, especially during breeding periods. Males may establish and defend territories, displaying aggression towards intruders. However, they are generally peaceful towards other tank mates and do well in a community setting with appropriate species.
Feeding and Diet
Charco Palma Pupfish are omnivores and can be fed a varied diet in captivity. They readily accept high-quality flake and pellet foods, as well as live or frozen fare such as bloodworms, brine shrimp, and daphnia. Offering a diverse diet ensures proper nutrition and health for these fish.
Reproduction & Dimorphism
During courtship, males display enhanced coloration and behavior to attract females for spawning. The female lays adhesive eggs in hiding spots provided in the aquarium. Males exhibit territorial behavior during breeding and will protect the eggs until they hatch. Sexual dimorphism is evident in the coloration and markings between males and females.
Habitat and Distribution
The Charco Palma Pupfish originates from the Ojo de Agua Charco Azul in Nuevo León, Mexico. This freshwater spring system was part of the Bolsón de Sandia fossil lake and housed various aquatic vegetation like Ceratophyllum and Typha. Unfortunately, due to water extraction, the area has dried up since the late 1990s, leading to the extinction of endemic Cyprinodon species within the habitat.
