Pseudohemiodon laticeps is a sand-dwelling whiptail catfish from the Paraná-Paraguay-Uruguay basins, reaching about 30 cm SL.
Compiled by Aquairi from published sources · Published · Updated
Overview
Pseudohemiodon laticeps is a whiptail catfish of the family Loricariidae, described by Regan in 1904. According to FishBase it occurs in the Uruguay, Paraná and Paraguay River basins of South America and reaches about 29.8 cm standard length.
Taxonomy
- Family: Loricariidae
- Genus: Pseudohemiodon
- Scientific name: Pseudohemiodon laticeps
Habitat
FishBase records the species as a freshwater, demersal fish of the Uruguay, Paraná and Paraguay basins, in subtropical conditions. It cites a temperature range of 24-28 °C and water hardness of 3-20 dH.
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 2.4. The KB record classifies the species as a carnivore fed once daily; this whiptail buries itself in fine soft sand and accepts live or frozen meaty foods.
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 (assessed 2020), with medium resilience.
Pseudohemiodon laticeps Breeding Guide
Overview
Pseudohemiodon laticeps, the Giant Whiptail, is a sand-dwelling loricariid distributed through the rios Uruguay, Parana and Paraguay, with records from southern Brazil, Paraguay and Argentina, per Seriously Fish. It reaches 250-300 mm standard length. Most remarkably, it is a paternal 'lip brooder' that has been bred in aquaria: the male carries the egg clutch attached to his lower lip until hatching.
Sexing
Tropical Fish Hobbyist notes that in these lip-brooding whiptails males have larger lips than females, a useful sexing tip. A conditioned female also fills out noticeably with eggs.
Conditioning
Seriously Fish describes the species as an opportunistic omnivore that, in captivity, needs regular meals of live or frozen Daphnia, mosquito larvae and chironomid (bloodworm) larvae alongside sinking dried foods. A meaty, varied diet brings adults into spawning condition.
Breeding Setup
This is a sand specialist that buries itself by day and feeds at night, so a soft, fine sand bed is essential, per Seriously Fish. Provide a spacious tank with sand, clean water at 18-24 °C, pH 6.0-7.5 and moderate hardness (around 36-215 ppm), with open feeding space at night.
Spawning Behavior & Trigger
After spawning, the male gathers the small clutch and holds the eggs attached to his labial barbels, as described by Seriously Fish and Tropical Fish Hobbyist. Remarkably, his behaviour is otherwise unaffected and he may burrow into the substrate with the eggs still attached. Lip-brooding clutches are small, typically only a few dozen eggs.
Egg & Fry Care
The male carries the eggs for 12-14 days, after which the fry hatch with a large yolk sac that is absorbed over roughly the next 48 hours, per Seriously Fish. Fry then accept Artemia (brine shrimp) nauplii, with a yield of 15-20 fry considered good. Successful breeders have tended to move the eggs to a separate tank just before hatching.
Common Challenges
Maintaining a soft, fine sand bed and clean water for a burrowing whiptail is essential; coarse substrate is unsuitable. Clutches are small, and the delicate timing of separating eggs before hatch makes consistent success difficult.
