Hypancistrus L297

A coded Hypancistrus form with a dark body and contrasting pale bands, spots or broken markings. Pattern variation makes accurate L297 provenance more useful than assigning an unconfirmed species name.

Use the L-number identification L297 together with the current assignment Hypancistrus sp. (L297). Do not merge it with visually similar forms without matching collection locality and diagnostic features. The L-number remains the principal stable identifier because the form is undescribed or not conclusively assigned.

Mature males generally develop a wider head and stronger cheek and pectoral odontodes. Females are fuller through the abdomen, while juveniles are difficult to sex.

Use warm, highly oxygenated water, strong filtration, rock or wood cover and multiple tight caves. Maintain clear records if other similar Hypancistrus are kept.

Nocturnal and territorial around caves, but usually peaceful toward unrelated midwater fish. Adult males may fight over shelter.

Can be kept singly. A pair or group requires several appropriately sized caves and enough floor area for every adult to feed without being trapped.

Mature males commonly defend caves and favoured feeding areas from similarly shaped loricariids.

Choose calm warm-water companions and avoid mixing similar coded Hypancistrus where accidental crossing would compromise lineage.

Maintain stable clean water with strong oxygenation. Warm water, protein-rich food, wood waste, and crowded hardscape can rapidly reduce oxygen and degrade water quality.

Feed a protein-rich omnivorous diet of quality sinking foods, crustacean and insect foods, with some vegetable matter. It is not an algae-control fish.

Feed after lights dim and distribute food near every occupied shelter. Confirm that subordinate fish eat and remove rich leftovers before they affect water quality.

Male-guarded cave spawning is expected for the genus, but reliable details for L297 are limited. Any offspring should retain accurate parental and L-number records.
