Dorsal Rubberlip Plecostomus L443

A broad, flattened rubberlip pleco with muted brown, grey or olive mottling that camouflages it against stone. Its enlarged lips and low body are suited to grazing in swift water.

Use the L-number identification L443 together with the current assignment Chaetostoma dorsale. Do not merge it with visually similar forms without matching collection locality and diagnostic features.

Mature males tend to develop a broader head and stronger cheek and pectoral odontodes. Females are fuller-bodied, but small fish are difficult to sex.

Use strong circulation, excellent oxygenation, smooth rocks, secure crevices and a clean substrate. Avoid prolonged high heat and dead areas where organic waste accumulates.

Usually peaceful with midwater fish but defensive over a favoured rock or shelter. It may remain in the strongest current for much of the day.

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 stream fish and avoid slow warm-water species or territorial plecos using the same rockwork. Each rubberlip needs its own grazing area.

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 vegetable and algae-based sinking foods, natural biofilm and occasional small invertebrate foods. Confirm that recently imported fish are feeding before they lose weight.

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.

Species-specific captive breeding information is limited. A guarded crevice is plausible, but repeatable methods should not be treated as established.
