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. "Wabenmuster" is a German aquarium trade name meaning honeycomb pattern. It carries no L-number. Imperial Tropicals writes that the common bristlenoses in the trade are probably line-bred from Ancistrus cirrhosus.
Morphology
Males of the genus develop branched tentacles on the snout, and females may grow short bristles (genus-level, as Imperial Tropicals also notes). The atlas has no description of the honeycomb pattern beyond the name.
Habitat
Sellers give only "South America" as the origin; both list it as captive bred. Wild habitat of this form is not documented.
Feeding
Imperial Tropicals recommends algae wafers, vegetables and occasional frozen foods. Ancistrus are grazers that rasp algae and soft wood (genus-level).
Mating
Like other Ancistrus, the genus spawns in caves, with the male guarding the eggs. Spawning of this form is not documented beyond its being sold as captive bred.
Breeding
Dan's Fish and Imperial Tropicals both sell it as captive bred.
In the aquarium
Imperial Tropicals lists a maximum size of 5 in, pH 5.0–8.0, 70–80°F, moderate hardness and a peaceful temperament. Dan's Fish lists an adult size of around 4–5 in and says Ancistrus like some water movement and hiding places, being nocturnal.
Conservation
No IUCN assessment exists for this undescribed form. Its range and numbers are not documented, so its conservation status cannot be stated.
