Snowflake Pleco L177 (Baryancistrus niveatus) Care Guide
Baryancistrus niveatus is a large spotted Loricariid pleco from the Tocantins and Xingu basins; a herbivorous biofilm grazer needing a spacious, warm, oxygen-rich tank.
Compiled by Aquairi from published sources · Published · Updated
Overview
Baryancistrus niveatus is a large suckermouth pleco of the family Loricariidae and the type species of the genus Baryancistrus (tribe Ancistrini). In the aquarium trade the light-spotted forms carry the L-number L177. Most species of the genus reach up to around 34 cm in total length and bear a membrane connecting the dorsal and adipose fins.
Taxonomy
- Family: Loricariidae
- Scientific name: Baryancistrus niveatus
- Subfamily: Hypostominae
- Common synonyms: L177, Snowflake Pleco
Habitat
FishBase records the species from the Tocantins, Xingu, Tapajós and Trombetas river basins in Brazil; the L177 form is associated with the Rio Xingu around the Rio Iriri confluence. Baryancistrus inhabit flowing, clearwater stretches, so the aquarium should offer warm, well-oxygenated water with moderate current and rocky or wooden hiding places.
Tank requirements
- Minimum tank volume: 400 L (106 gal)
- Adult size: 25-30 cm (9.8-11.8 in)
- Temperature: 24-28 °C (75-82 °F)
- pH: 6-7.5
- GH: 2-12 °dGH
- Lifespan: 8-12 years
Diet
The genus is mainly herbivorous and detritivorous, grazing algae and biofilm and needing food available throughout the day. A vegetable-rich diet (blanched vegetables, spirulina) plus the biofilm growing on wood and rock suits it, with only modest amounts of meatier foods.
Compatibility
It keeps to the bottom and is peaceful toward unrelated fish, but males of the genus can be strongly territorial toward one another and may fight on sight. Keeping more than one specimen requires generous space and visual barriers of rock and wood. It mixes with calm mid-water fish such as tetras and Corydoras.
Breeding
Sexing is difficult even in adults, and most Baryancistrus species have probably not been bred in captivity.
Conservation status
The IUCN Red List assessed the species as Vulnerable (2022).
Breeding Baryancistrus niveatus (L177)
Overview
Baryancistrus niveatus is a large suckermouth catfish in the family Loricariidae, subfamily Hypostominae, and is the type species of the genus (originally Hypostomus niveatus Castelnau, 1855). It is offered in the hobby under the L-number L177. FishBase records a maximum size of about 34 cm total length, and the genus inhabits flowing, often clearwater sections of the Tocantins, Xingu, Tapajós and Trombetas river basins in Brazil. On the IUCN Red List the species is assessed as Vulnerable (2022).
Sexing
No reliable sexing criteria for B. niveatus are documented in the consulted sources; FishBase reports its maximum size for "male/unsexed" specimens and provides no maturity data.
Breeding Setup
FishBase characterises the species as a freshwater, demersal (bottom-associated) tropical fish. Because the genus occupies flowing, oxygen-rich clearwater rivers, any attempt to maintain adults would require a large tank reproducing those conditions, but no spawning protocol has been established for this species in the sources reviewed.
Common Challenges
The principal challenge is that there is no verified record of this species reproducing in aquaria, so no trigger, clutch size, or fry-rearing data exists to follow. Its large adult size and Vulnerable conservation status further argue against casual breeding attempts.
