This Hypancistrus was collected in Rio Aripuanã, Brazil, in 1997. It was presented in DATZ 4 years later, in the form of a rather poor “in hand out of water” picture. It was not seen again until late 2015. Rupert Collins then presented new photos of better quality, revealing a nicer fish than first thought. In early 2016, German importer Panta Rhei succeeded bringing some specimens of L297 to Europe, which hopefully means the species will be established in our hobby.

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.
