The Green Dragon Bristlenose Pleco (Ancistrus sp.) is a highly sought-after, captive-developed strain of bristlenose catfish prized for its flowing, elegant fins and unique, mottled camouflage-green coloration. Unlike common plecos that quickly outgrow most home setups, this domestic variety stays at a manageable size of 4 to 6 inches, making it an exceptional, functional centerpiece for community tanks. Key Care Requirements Tank Size: A minimum of 30 gallons is required to accommodate their growth and provide enough surface area for foraging. [1, 2, 3, 4] Water Parameters: They thrive best in a temperature range of 72°–86°F, a pH of 6.5–7.5, and stable water conditions. [1] Aquarium Decor: Driftwood is mandatory. They need to chew on wood to extract essential cellulose for digestion. Provide plenty of caves, rocks, and live plants to mimic their natural habitat and give them secure hiding spots. [1, 2, 3, 4, 5] Diet: While they are excellent algae eaters, they are omnivores that lean heavily herbivorous. Supplement their diet daily with sinking high-quality veggie tabs, spirulina wafers, and regular blanched vegetables like zucchini or cucumber. [1, 2, 3] Compatibility: They are incredibly peaceful community fish but can be vulnerable to aggressive tankmates or fin-nippers (like Tiger Barbs) that target their trailing fins. They can also be territorial with other male plecos unless given a very large tank. [1, 2]
