Ancistrus sp.

Several species of the bristlenose are sold in commercial outlets under a confusing variety of names. Mature males can be distinguished by the presence of long barbels on the head. Ancistrus browses encrustant algae. The female deposits her eggs on carefully selected sites, though captive breeding is rare. Size: 13 cm.
