Nocturnal Dwarf Panaque L329

A dusky wood-eating pleco with a dark brown body and subdued bands or mottling that provide camouflage among submerged branches. It is especially secretive during daylight.

Use the L-number identification L329 together with the current assignment Panaqolus nocturnus. Do not merge it with visually similar forms without matching collection locality and diagnostic features.

Mature males develop stronger odontodes on the cheeks, pectoral region and rear body. Females are generally fuller through the abdomen, while juveniles are difficult to sex.

Provide permanent driftwood, several tight caves, shaded cover and efficient filtration. Wood-rich feeding creates a steady load of fine waste even when the fish remains modest in size.

Usually shy and peaceful with other fish, but males can defend caves and preferred wood. Activity increases after dark and during feeding.

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.

Suitable for calm communities when each pleco has a separate shelter and direct feeding access. Soft-leaved plants may be rasped.

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.

Wood must always be available, supported by fibre-rich vegetable foods, algae wafers and limited invertebrate protein. Too much rich animal food is inappropriate for a wood-adapted digestive system.

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 achievable. The male guards the eggs and early fry, which require clean water, wood, biofilm and suitable plant-rich foods.
