In short: 12 to 15 cm as an adult, 100 L minimum, water between 22 and 27 °C. A peaceful, nocturnal armored catfish, it hides by day and a single male rules the tank's cavities. Driftwood to rasp is vital for its digestion, and tank algae are never enough: supplement with blanched vegetables.
Feeding a Bristlenose pleco: diet and habits
The Bristlenose pleco is mainly herbivorous: blanched greens, plant-based granules and algae — over-rich protein foods clog its system. Since it eats at the bottom, pick sinking wafers and stop at what gets eaten in two minutes: beyond that you are feeding the water, not the fish.
Frequency and variety
One or two small feeds a day for adults, with a weekly fasting day that costs it nothing — overfeeding remains the top cause of tank pollution. Feed at a fixed time: the Bristlenose pleco learns the ritual fast, and you get the best observation window. Alternate dry, frozen and blanched greens (courgette, spinach) across the week.
The costly mistakes
The Bristlenose pleco “begging” at the glass is not starving — it has simply learnt your silhouette: hold the two-minute line. Budget flakes crumble and pollute: serious-brand food costs a few euros more per year, not per month. The rest of the profile is on the full Bristlenose pleco profile.
