L397 Panaqolus – Species Profile, Care Requirements & Husbandry Overview

L397 (Panaqolus sp.) – A Distinctive Wood-Eating Pleco from Brazil

The L397 Panaqolus is a striking and highly recognizable member of the Loricariidae family, characterized by its warm brown coloration and bold patterning.
Originating from the region of Pará in Brazil, this species inhabits fast-flowing, oxygen-rich waters and thrives in aquarium environments that replicate these natural conditions.

This profile outlines the essential care standards, environmental requirements, and feeding protocols for maintaining L397 successfully in a long-term aquarium setting.

Natural Habitat

L397 occurs in clear, oxygen-rich streams with moderate to strong current.
The environment typically contains:

  • large amounts of driftwood
  • root structures
  • rocky areas
  • shaded zones and underwater crevices

Replicating these features in the aquarium is essential for long-term success.


Behavior & Compatibility

The L397 is generally peaceful, though notably assertive when competing for food or preferred resting spots.
It integrates well into most community aquariums and coexists safely with:

  • peaceful tetras
  • livebearers
  • dwarf cichlids
  • catfish
  • dwarf shrimp (with sufficient structure)

Despite its calm nature, its strong feeding drive can intimidate more passive species during feeding time.


Tank Setup & Requirements

1. Minimum Tank Size

A tank from 120 cm length is recommended, especially for adult individuals or groups.

2. Hardscape & Layout

L397 depends heavily on wood for both nutrition and digestion, making it essential to include:

  • soft woods (e.g., bogwood, mopani, driftwood)
  • root structures
  • caves and shelters
  • open sand areas

Plants are not required, but robust species such as Anubias, Java fern or Bucephalandra can be used for additional structure.

3. Water Conditions

Maintain:

  • pH 5.5–7.0
  • soft to medium hardness
  • high oxygen levels
  • stable warm temperatures (27–30°C)

Due to their natural habitat, strong filtration and regular water changes are essential.
Additional oxygenation via air stones or an oxydator is recommended.


Feeding Strategy – Primarily Wood-Eaters

L397 belongs to the group of xylophagous Plecos, meaning wood plays a central role in their diet and digestion.

Provide:

  • soft driftwood (Moorkienholz highly recommended)
  • plant-based foods
  • blanched vegetables (zucchini, pumpkin, spinach)

Although predominantly herbivorous, they readily accept:

  • small portions of mussel meat
  • occasional carrion or leftover protein sources

A varied diet encourages strong coloration and healthy growth.


Breeding Panaqolus sp. (L397)

Breeding attempts have been successful in aquarium settings.
Key characteristics:

  • cave breeders
  • males guard eggs until hatching
  • stable warm water improves spawning success
  • fry accept fine powdered foods and crushed tabs

Young fish are typically available at 4–5 cm, and sexing juvenile L397 is not reliably possible.


Summary

The L397 Panaqolus is a visually appealing and behaviorally interesting Pleco that adapts well to community aquariums, provided its need for wood, oxygen-rich water, and strong filtration is met.
With proper care, it reaches up to 15 cm and displays long-term stability, making it a rewarding choice for dedicated aquarium keepers.
