L364 Baryancistrus Plecostomus

L364 is an unidentified Baryancistrus with a broad mouth, compact armoured body and spotting or mottling that may change with age. Similar coded forms can be difficult to separate without collection records.

Use the L-number identification L364 together with the current assignment Baryancistrus sp. (L364). 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 usually develop a broader head and stronger cheek and pectoral odontodes. Females become fuller through the abdomen, but juveniles are not reliably sexed.

Provide warm, highly oxygenated water, strong filtration, broad rock or wood grazing surfaces and several secure caves. Recently imported fish require close observation because poor feeders can lose condition quickly.

Often shy at first but territorial around caves and preferred feeding surfaces. Adults may become forceful with other plecos when bottom space is limited.

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.

Peaceful midwater fish are usually suitable. Other loricariids require separate shelters, visual barriers and protected feeding areas.

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.

Offer abundant vegetable and algae-based sinking foods, soft vegetables and biofilm, with modest invertebrate protein. Visible algae is not a complete diet.

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.

A male-guarded cave spawning method is expected, but dependable breeding guidance for this coded form remains limited. Mature compatibility and excellent oxygenation are essential.
