Description
IMPORTANT: a true common pleco (Hypostomus plecostomus) reaches 40–50 cm in the aquarium and needs at least 380 L. For most home tanks under 200 L the bristlenose (Ancistrus sp.) is the right pick — see its own profile.
Juveniles of several species are sold as 'pleco' — Pterygoplichthys, Glyptoperichthys, and others. Always confirm the species when buying.
Care
Volume
From 380 L for one adult. Driftwood is mandatory: plecos rasp wood and this is an essential part of their digestion.
Feeding
Plant-based diet: sinking spirulina tablets, blanched zucchini, cucumber. Protein supplement 1–2 times a week (bloodworm).

FAQ
- Подходит ли пленко для 100-литрового аквариума?
- Нет. Hypostomus plecostomus вырастет до 40+ см и быстро перерастёт объём. Для небольших аквариумов выбирайте анциструса (Ancistrus sp.) — до 15 см.
