The L183 Starlight Bristlenose Pleco (Ancistrus dolichopterus), also known as the White Seam Bristlenose Pleco, is a member of the Loricariidae family of South American suckermouth catfishes. This Pleco is easily bred in home aquariums. Its facial area becomes adorned with many bristle-like appendages beginning in sub-adulthood. Both sexes grow the appendages, but the growth and length is much more pronounced in males.
A generally peaceful and hardy species, the Starlight Bristlenose Pleco is an excellent, undemanding candidate for most aquariums. The Starlight Bristlenose Pleco grows to a size of only 10 to 15 cm. This smaller size makes for a much more manageable (and less messy) pleco that can thrive permanently in a well-maintained aquarium as small as 150L. Male plecos may be somewhat territorial with other males of their species, but disputes can usually be diffused by providing ample territory and hiding places for each fish.
