Remarks:  The marbled whiptail is said to be one of the most widespread whiptail species in regards to distribution, able to be found in Brazil, Peru, and other nearby countries in South America. Because of this varying range in habitat, these fish are rather adaptable compared to their cousins, tolerating a wider range in regards to water hardness and pH. They are similar to the chameleon whiptail in that they change their pattern rather quickly in response to their environment and mood. When on a lighter substrate, they can turn totally white if frightened or trying to blend in. A darker substrate tends to result in darker "mask" and bands along the tail.

  This species has a rather fascinating way of caring for their offspring. After mating, the male marbled whiptail gathers up the eggs in his whiskers to hold onto. He will aerate the eggs with his mouth parts, keeping them healthy and safe until the fry hatch and are free swimming when he releases them. In captivity, the fry are very sensitive to change and are prone to starvation so small, frequent water changes should be performed and lots of nutritious food provided.

 Like other whiptails, they have long whiskers that help them during feeding and spawning. Their dorsal and caudal fins have long, thin trailers that make for an impressive display. To preserve these sensitive structures, the marbled whiptail should be kept on soft sand and nippy tankmates should be avoided. They are a rather shy and passive species, so extra care should be taken to ensure they get enough to eat. With them being carnivore leaning omnivores, a varied diet of mostly protein rich foods should be provided.
