Taxonomy & naming
This is an undescribed form: no scientific name, authority or type material stands behind it, and its identity and range are not documented in the sources the atlas uses. L010a is an L-number, the coding system DATZ magazine began in 1988 for imported loricariids that could not be identified. Dan's Fish sells it as the L10A red lizard whiptail and Aqua Haus Gaus as the "Roter Hexenwels" L10A. Imperial Tropicals says it is not known where the fish comes from or whether it occurs naturally, and that most keepers consider it a hybrid or line-bred variant of the similar Rineloricaria lanceolata. That is the seller's view, not a published identification.
Morphology
The common name describes a red coloration. Imperial Tropicals says an occasional fish with a more natural brown colour shows up in spawns. Rineloricaria are slender, flattened whiptail catfish with a long, thin tail (genus-level).
Habitat
No wild locality is documented. Rineloricaria live in South America, in streams and rivers over sand and leaf litter (genus-level). Imperial Tropicals says all specimens in the trade are captive bred.
Feeding
Rineloricaria are generally fed sinking foods, including vegetable matter and small meaty items (genus-level); this form's diet is not documented.
Mating
Rineloricaria are cave or crevice spawners in which the male guards the eggs (genus-level). Spawning behaviour of this form is not described.
Breeding
Dan's Fish sells it as aquarium bred and raised, and Imperial Tropicals says all available fish are captive bred. The atlas holds no spawning details.
In the aquarium
Dan's Fish lists shipped fish at 1 to 2 inches (about 1–2 in) and an adult size of around 4 to 5 inches (about 4–5 in), and calls the fish as pretty and peaceful as a catfish can be. These are seller figures.
Conservation
No IUCN assessment exists for this undescribed form. Its range and numbers are not documented, so its conservation status cannot be stated.
