Overview
Family: Loricariidae
Bristlenose Plecos (Ancistrus spp.) are among the most popular and hardy algae-eating fish in the hobby. Native to South American streams, they are smaller and more manageable than common Plecos, making them perfect for medium-sized aquariums. Males develop distinctive bristles on their snouts, used for display and territory defense. They are reasonable algae eaters, mostly active at night, and thrive in tanks with driftwood, caves, and stable water conditions.
Recommended Tank Size: A minimum of 60 litres
- Peaceful bottom dwellers that mix well with most community fish such as tetras, rasboras, corydoras, small cichlids, and peaceful livebearers
- Provide driftwood, caves, and hiding spaces for shelter and breeding
Average Adult Size:
- Body length: 10-15cm
- Reach adult size within 12–18 months
- Grow quickly in the first 6 months
- Males often start to develop bristles once they reach 4 - 5 cm
Water Parameters:
- pH: 6.5–7.8
