Relevant Information:

Description: Head and predorsal uniformly dark brown in larger individuals and marbled in young. Head depth, 2.3-3.3 times in SL; body depth 1.9-3.2 times in SL. Belly totally naked except for thoracic plates and a group of small irregular plates concentrated on the anus, just posterior to pelvic-fin insertion. Rictal barbels small, attached to lower lip by small membrane. Stomach indistinguishable; intestine very long, about 14 times in SL. Keeled lateral plates, 29-30. Colouration: Caudal fin with two small dark black blotches at tip of upper lobe and only one on tip of lower lobe; point of confluence of the lateral keels at 20-22nd. Dorsal fin with large black spot on its distal end. Other fins spotted except the anal fin. Aquarium Care: Not the easiest genera to keep as they will need clean, oxygen rich water and a strong current. Does not do well in imports due to its difficulty in traveling containers. Sexual Differences: Males tend to have odontodes (hair like structures) on the first ray of the pectoral fins and the head in males is broader. Diet: Dry foods, algae wafers, Spirulina and normal tablet foods. Frozen foods, Artemia nauplii, glass worms and Daphnia. Etymology: The specific name guianensis: –ensis, Latin suffix denoting place: French Guiana, where it is endemic.

IUCN Red List

Although precise estimates of the current population sizes of Harttia guianensis are not known, based on the spatial and temporal quantification of the records in the bibliographic review, and of collections, it is considered that its population abundance is low in most of its area of distribution, although it can be highly abundant in well-preserved habitat. And although the species' range may be impacted by mining activities, the species occupies a moderately large distribution across Suriname and French Guiana. As such, it is currently assessed as Least Concern (LC), (IUCN 2023).
