Sales Description

The White Tip Longfin Bristlenose Pleco is a rare and elegant variant of the beloved Ancistrus species, prized for its graceful flowing fins and distinctive white fin tips. Its elongated fins ripple beautifully as it glides along surfaces, creating a striking visual display that adds both movement and refinement to planted aquariums. The white fin tips stand out dramatically against its darker, mottled body, making it a true showpiece for collectors and aquascaping enthusiasts.

Like all Bristlenose Plecos, this variety is hardy, algae-grazing, and well-suited for community aquariums. Its manageable size and peaceful temperament make it a better choice than larger pleco species for smaller tanks. This fish not only helps control algae but also contributes natural character to the aquarium with its gentle behavior and striking appearance.

Care Guide

White Tip Longfin Bristlenose Plecos thrive in well-filtered aquariums with moderate flow and ample hiding spots. A tank size of at least 20–30 gallons is recommended for one adult, with driftwood, caves, and plants for shelter. Driftwood is especially important as it provides fiber that aids in digestion.

They prefer temperatures between 74–82°F (23–28°C), a pH of 6.5–7.8, and soft to moderately hard water. Stable water conditions and regular maintenance are key to keeping their long fins healthy and free from damage.

Although they are known for their algae-eating habits, they should also be offered a varied diet. Feed sinking algae wafers, blanched vegetables such as zucchini or cucumber, and occasional protein-based foods like shrimp pellets or bloodworms. A balanced diet will enhance both growth and color intensity.

Breeding Notes

Breeding follows the same pattern as other Ancistrus species. Males develop characteristic facial bristles and guard the eggs laid in caves or crevices. Providing multiple hiding spots encourages natural spawning behavior. The male fans and protects the eggs until they hatch, after which the fry can be fed blanched vegetables or crushed algae wafers.

Compatibility

This species is peaceful and works well in most community setups. Avoid keeping multiple males in small tanks to prevent territorial disputes, especially during breeding. Ideal tankmates include tetras, rasboras, corydoras, dwarf cichlids, and other calm species.
