Furunculus Hypancistrus L199

A compact Hypancistrus with a dark body patterned by pale bands, saddles or broken markings. Pattern strength varies, so confirmed provenance is useful when separating it from similar coded forms.

This profile is identified by L199 and the current assignment Hypancistrus furunculus. Do not merge it with a visually similar L-number without matching collection locality and diagnostic features.

Mature males generally develop a wider head and stronger odontodes on the cheeks and pectoral fins. Females are fuller through the abdomen, but juveniles are difficult to sex.

Provide warm, clean and highly oxygenated water with rockwork, wood and several tight caves. Strong filtration is needed to support a protein-rich diet without allowing waste to accumulate.

Mostly nocturnal and territorial around caves. It is normally peaceful with unrelated midwater fish but may fight similar plecos over shelter.

Can be kept singly or in a managed breeding group if each adult has an appropriate cave and unobstructed feeding access.

Mature males defend caves and may trap or injure rivals when shelter is limited.

Use calm warm-water companions and give each pleco a separate cave and feeding area. Avoid mixing uncertain Hypancistrus forms if preserving lineage matters.

Maintain stable, clean, oxygen-rich freshwater. Strong filtration and gas exchange are essential because warm water, protein-rich feeding, and loricariid waste can reduce oxygen and impair water quality.

Feed quality protein-rich sinking foods, small crustacean and insect foods, with some vegetable matter. It should not be expected to control algae.

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

Male-guarded cave spawning is possible for this species, but breeding remains a specialist project. Mature compatibility, tight caves and clean oxygenated water are central to success.
