Pseudohemiodon apithanos is a sand-dwelling whiptail catfish from the western Amazon, reaching about 14.5 cm SL.
Compiled by Aquairi from published sources · Published · Updated
Overview
Pseudohemiodon apithanos is a whiptail catfish of the family Loricariidae, described by Isbrücker and Nijssen in 1978. According to FishBase it originates from the San Miguel River basin in the western Amazon drainage. It is sometimes called the chameleon whiptail.
Taxonomy
- Family: Loricariidae
- Genus: Pseudohemiodon
- Scientific name: Pseudohemiodon apithanos
Habitat
FishBase records the species as a tropical freshwater, demersal fish from the San Miguel River basin in the western Amazon drainage of South America.
Tank requirements
- Minimum tank volume: 300 L
- Temperature: 24-28 °C (75-82 °F)
- pH: 6.0-7.5
- GH: 2-12 °dGH
- Lifespan: 8-12 years
Diet
FishBase assigns a trophic level of about 2.5. The KB record classifies the species as a carnivore fed once daily; fine-grained sand and meaty foods suit this bottom-feeding whiptail.
Compatibility
A peaceful, nocturnal, bottom-dwelling species. The KB record lists tetras and Corydoras as compatible, while aggressive or territorial plecos should be avoided.
Conservation status
FishBase lists the IUCN Red List status as Least Concern, with medium resilience and low vulnerability to fishing pressure.
Pseudohemiodon apithanos Breeding Guide
Overview
Pseudohemiodon apithanos, the Chameleon Whiptail, lives in the upper Amazon basin of Peru and Ecuador and reaches a maximum 14.5 cm standard length, per Wikipedia. Like other members of its genus it is a paternal lip-brooder: the male carries the egg clutch attached to his lower lip until hatching. Species-specific breeding reports are limited, so genus-level behaviour from the congeneric P. laticeps is referenced.
Sexing
In lip-brooding whiptails such as Pseudohemiodon, Tropical Fish Hobbyist notes that males have larger lips than females, a useful sexing aid. A gravid female fills out with eggs.
Conditioning
For the genus, Seriously Fish describes Pseudohemiodon as opportunistic omnivores that need regular live or frozen Daphnia, mosquito larvae and bloodworm alongside sinking dried foods. A varied meaty diet conditions adults.
Breeding Setup
Pseudohemiodon are sand-dwellers that bury by day and feed at night, so a soft, fine sand bed and clean water are essential (Seriously Fish). Provide a spacious tank with open sand and gentle, well-filtered flow. As a colour-changing whiptail it matches a sandy substrate well.
Spawning Behavior & Trigger
As a paternal lip-brooder, after spawning the male gathers the small clutch and holds the eggs on his labial barbels, and may continue to burrow into the sand with the eggs attached, as documented for the genus by Seriously Fish and Tropical Fish Hobbyist. Lip-brooding clutches are small, typically only a few dozen eggs.
Egg & Fry Care
Following the genus pattern (Seriously Fish, P. laticeps), the male carries the eggs about 12-14 days, after which the fry hatch with a large yolk sac absorbed over roughly 48 hours. Fry then accept Artemia nauplii. Precise figures for apithanos are not separately documented, so genus values are cited explicitly.
Common Challenges
Providing a soft sand bed and clean water for a burrowing whiptail is essential. Small clutch sizes and the delicate handling of brooding males make captive breeding difficult and infrequently reported.
