Our Guide To Keeping L519 Honeycomb Bristlenose Pleco
-
About Fish Species:
- Scientific name: Ancistrus sp. “L519”
- Common name: Honeycomb Bristlenose Pleco
- Family: Loricariidae
- Origin: Upper Río Negro, Colombia
- Adult length: 10 to 12 cm
- Lifespan: 5 to 8 years
- Diet: Herbivore (with omnivorous tendencies)
- Care Level: Easy
- Temperament: Peaceful
-
Tank Setup:
- L519 Honeycomb Bristlenose Plecos enjoy a tank with driftwood, smooth rocks, and plenty of hiding spots such as caves or coconut shells.
- A minimum tank size of 80L is suitable for a single adult, with more space required for multiple individuals.
- Dim lighting and soft substrate mimic their natural blackwater habitat.
-
Water Parameters:
- pH range: 5.5 to 7.2 (slightly acidic preferred)
- Temperature range: 24 to 28°C (75 to 82°F)
- Water hardness: Soft to moderately hard
-
Filtration and Water Flow:
- Moderate filtration is important. Ensure good oxygenation and minimal nitrate buildup as this species prefers pristine water conditions.
- A gentle to moderate flow is preferred, replicating slow-moving river habitats.
-
Diet:
- Primarily herbivorous, they feed on algae and plant matter. Algae wafers, spirulina-based sinking pellets, and fresh vegetables like courgette and spinach are ideal.
- Occasional protein from bloodworms or brine shrimp can be offered in moderation, especially during breeding.
-
Tank mates:
- Peaceful community fish such as tetras, rasboras, dwarf cichlids, and other small South American species are ideal companions.
- Avoid fin-nippers or highly territorial fish that may stress the bristlenose.
-
Behavior and Compatibility:
- L519s are peaceful and typically stay near the bottom of the tank, active mostly during the night or in dimly lit conditions.
- Males may show territorial behavior during breeding, especially around cave sites, but otherwise are non-aggressive.
- They do not require schooling but can coexist with other peaceful bottom dwellers given enough space and cover.
