Undescribed speciesPlecostomus

Countries of origin

Good fit for your tank?

Good fit for

  • A mature stream aquarium with strong oxygenation
  • A rock-focused setup allowed to develop biofilm
  • A keeper experienced with rheophilic catfish

Think carefully if

  • The aquarium remains warm with weak flow
  • Territorial bottom fish already occupy the rocks
  • You require a predictable breeding method

L408 Chaetostoma Plecostomus is a South American loricariid represented by L408. It requires stable oxygen-rich water, suitable caves, and deliberate species-appropriate feeding.

Appearance and Identification

L408 is an unidentified rubberlip pleco with a broad head, flattened underside and muted mottled or spotted camouflage. Its enlarged lips and body shape are adapted to grazing stone in moving water.

Use the L-number identification L408 together with the current assignment Chaetostoma sp. (L408). 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.

Adult males generally develop a broader head and stronger odontodes around the cheeks and pectoral region. Females become fuller through the abdomen, while juveniles are difficult to sex.

Tank Requirements

Jumping risk
Low

Provide strong oxygenation, brisk current, smooth stones, secure crevices and excellent water quality. Avoid prolonged high heat and stagnant areas where organic waste collects.

Behaviour and Tankmates

Usually peaceful with midwater fish but territorial over favoured grazing stones and shelters. It may spend long periods in the strongest flow.

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 peaceful current-loving fish and avoid aggressive plecos or slow species that need much warmer, calmer water. Multiple rubberlips require distinct territories.

Stability importance
Critical

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.

Parameter caveat
Acclimate slowly to temperature and conductivity changes. Keep ammonia and nitrite at zero, control nitrate, and inspect caves and rockwork for trapped waste.

Feeding

Diet types
Algae Grazer, Aufwuchs Grazer, Herbivore, Omnivore
Feeding frequency
Daily
Preferred foods
  • Natural aufwuchs and biofilmMaintain mature rocks and wood for continuous supplementary grazing.
  • Complete herbivore or algae waferUse a high-quality sinking staple with fibre.
  • Blanched leafy greens or courgetteOffer occasionally and remove leftovers.
  • Frozen daphnia or insect larvaeUse small portions as supplementary protein.

Offer algae and vegetable-rich sinking foods, natural biofilm and modest amounts of small invertebrate foods. Recently imported fish should be watched closely to confirm feeding.

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.

Breeding

Brood or egg count
Usually several dozen adhesive eggs; dependable species-specific fecundity data are unavailable.

Baby foods
  • Mature biofilmProvides continuous grazing after fry leave the cave.
  • Fine powdered sinking foodFeed tiny portions close to shelter several times daily.
  • Newly hatched brine shrimpUse as supplementary protein once fry can take moving prey.

Detailed captive-breeding information for this coded Chaetostoma is limited. A guarded crevice or cave is likely, but it should be treated as an advanced breeding subject.
