Species profile
Baryancistrus chrysolomus
Common names: Mango Plecostomus L047, L047
Mango Plecostomus L047 is a South American loricariid represented by L047. It requires stable oxygen-rich water, suitable caves, and deliberate species-appropriate feeding.
A dark, largely plain Baryancistrus with broad yellow to golden seams along the dorsal and caudal fins. Unlike spotted gold-nugget forms, the adult body remains comparatively uniform.
Use the L-number identification L047 together with the current assignment Baryancistrus chrysolomus. Do not merge it with visually similar forms without matching collection locality and diagnostic features.
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.

Manual aquarium siphon and gravel cleanerA manual siphon for routine aquarium water changes and accessible waste removal. The seller lists a hose approximately 1.6 m long.
Control the flow and keep the intake clear of fish and delicate planting. Clean the areas appropriate for your substrate and layout rather than disturbing the entire planted bed.
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.
Captive cave spawning is possible but demanding. A mature male guards the clutch, while warm oxygen-rich water and careful management of eggs and fry are essential.
