🐠Bristlenose pleco: gear and buying guides

Mostly nocturnal and an algae grazer, it requires driftwood to rasp on, essential for its digestion, in a tank of at least 100 L between 22 and 27 °C. Males sport the characteristic bristles on their snout.

Bristlenose pleco gear, family by family

• 🍖 Food

  Tank algae are never enough: supplement with vegetable wafers, blanched zucchini and cucumber. Rasped driftwood provides fiber essential to its digestion.

• 🧴 Care & grooming

  Undemanding about hardness but sensitive to low oxygen in warm water: ensure good circulation. Remove uneaten vegetables after 24 hours to prevent pollution.

• 🎾 Toys & enrichment

  Driftwood is mandatory, along with caves and upturned coconut shells where it spends its days. Males claim a narrow cavity, also used for spawning.

• 🏠 Bedding & habitat

  A tank of at least 100 L with several shaded shelters, as it avoids bright light during the day. One male per medium tank, since two males fight over hiding spots.

• 🧳 Travel & safety

  Its pectoral spines snag in nets and pierce bags: handle it with a rigid container and a double bag. Standard 30-minute acclimation.

• 🧰 Accessories

  A generously sized piece of driftwood, sinking wafers, a ceramic spawning cave and a vegetable clip. Expect 20 to 50 euros of dedicated accessories on top of the tank equipment.
