Relevant Information:

First introduced in the DATZ magazine of August 1989. Little is known about this species except that it was taken from the rapids along with Metaloricaria paucidens. Description: Its morphology is intermediate to that of Cteniloricaria maculata and Hartia surinamensis. The appearance of its abdominal plaque is retarded and its caudal fin's shape is similar to that of the other two species. As far as the body shape is concerned, it appears to be closer to H. surinamensis than to C. maculata, thus justifying its move to the genus Harttia. 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 fowleri: In honour of Dr. Henry Weed Fowler.

IUCN Red List

Harttia fowleri has its distribution along the Oyapock/Oiapoque River drainage in French Guiana and Brazil. The extent of occurrence (EOO) is estimated at 23,282 km2 and the area of occupancy (AOO) at 16,064 km2. There are some local threats of pollution, increase of sediment, and agriculture activities that impacts the ecosystem. Additionally, there are illegal gold mining activities in French Guiana. However, the overall area of the distribution is broad and it seems to be relatively well preserved with no potential impacts. Thus, Harttia fowleri is assessed as Least Concern (LC), (IUCN 2022).
