Hypancistrus sp. L474
Identical to Hypancistrus debilittera (L129) or not? L474 is from a different river, Rio Cinaruco, than H.debilittera (Rio Bita). It was first imported by Aqua Global in Germany in 2014. It has slightly more teeth in the upper jaw than L340, but fewer than L129. Clearly the H.debilitera complex is represented by several similar but slightly different forms in the rivers of the border area between Venezuela and Colombia. L474 is currently very new in the hobby, so it's barely known or kept outside Germany.
Facts:
Name: Hypancistrus sp. “L474”

Keeping L474 and the other, similar forms separate will become a big challenge for breeders in the future. It will be very important to keep track of the lineage when these are purchased, to avoid unwanted crossbreeds of the various forms.
They need an aquarium set up consisting of lots of hiding places in the form of rocks, wood and of course specially made caves that suit their measurements. In these the males will eventually guard their offspring. They prefer water that is fairly warm (27-30 C), soft and slightly acidic. Most of all it should be well oxygenated and clean, so a good filtration system and frequent water changes are essential. Among themselves they are fairly peaceful, although males may quarrel for caves and females can sometimes be badly injured or even killed during the breeding-trapping in the male's cave. Males develop longer odontodes on their pectoral fins and on their cheeks, and have broader heads. Hypancistrus are mostly carnivorous, so a selection of crustaceans, insect larvae and fish meat should be offered along with high quality dried foods that also contain some vegetable matter.
