Panaqolus albivermis
A small pleco with fine white vermiculations over a dark brown body, known only from the San Alejandro River in Peru. It eats wood, so driftwood is essential. The IUCN assesses it as Endangered.
Panaqolus albivermis is a small loricariid catfish known only from the San Alejandro River in the Ucayali drainage of Peru, with its type locality in the Irazola District of Padre Abad Province. FishBase records 9.6cm standard length. Fine white vermiculations run over a dark brown body, and the specific name albivermis refers to that pattern. Although not described until 2013, it has been known to aquarists since at least 1996 and is traded as the flash pleco or by its number, L-204. The IUCN assesses it as Endangered because it occupies a single location where it is collected in large numbers for the aquarium trade, which has driven a population decline. Like the related clown pleco it rasps and eats wood, so driftwood must be kept in the tank as food rather than decoration.

Driftwood, vegetables and sinking vegetable-based wafers
A small species of about 10cm. Always include several pieces of softer driftwood and build cave-like retreats. The wood-based diet produces a lot of waste, so allow generous filtration.
The type locality is a tropical river in the upper Amazon drainage of Peru. The wood-based diet produces a lot of waste, so keep water quality up with good filtration and regular water changes.
It is a small bottom-dweller, so pairing it with fishes that occupy other levels is the usual approach.
Panaqolus species rasp and eat wood. Keep driftwood available at all times and supplement with vegetables and sinking vegetable-based wafers.
Captive breeding records are scarce. The species is confined to one locality and declining under collection pressure, so keep any fish obtained with long-term care in mind.
The IUCN assesses it as Endangered, citing heavy collection for the aquarium trade from a single locality as the driver of decline. It is not listed by CITES. Running out of driftwood readily causes digestive problems.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The average lifespan of Flash Pleco is 6-10 years. With proper care and nutrition, they can live a long and healthy life.
Flash Pleco typically reaches 9-10cm as an adult. Size may vary depending on care conditions and individual genetics.
Flash Pleco feeds on: Driftwood, vegetables and sinking vegetable-based wafers. Aim for a balanced diet with appropriate feeding frequency.
