Peppermint Bristlenose
Ancistrus sp. — Peppermint Variant
 
Overview
The Peppermint Bristlenose is a premium Ancistrus variety prized for its deep black body covered in fine, bright white speckles resembling “peppermint.” Hardy, peaceful, and small-growing, this bristlenose is a favourite among aquarists for planted tanks, community aquariums, and specialty pleco setups.
Its striking colour contrast and excellent algae-grazing behaviour make it both beautiful and practical. A perfect choice for hobbyists wanting something more unique than the common bristlenose.
