Description: Rineloricaria zaina is distinguished from other species of the genus by the following combination of characters: the tip of the snout with a bare area oval not extending posteriorly; dorsal crests and head inconspicuous; abdomen completely covered by 5-6 small plates and uniform series, preceded by for smaller boards and numerous in the waist shoulder strap; preanal plate; pectoral fins reaching the first third of the pelvis; pelvic beyond the anal fin origin; dark range in the posterior margin of the caudal fin. This species looks like R. jaraguensis by abdomen covered with plates, but is easily this at the lowest head size (22.4% vs. 25.9 -26.6 -24.8% CP); differs from R. thrissoceps (also with abdomen interorbital distance largely covered) ( -26.6 22.1% vs. 19.8% in CC); R. quadrensis, R. felipponei, R. steindachneri and R. henselli differ to R. zaina with the same characteristics that R. anitae. Rineloricaria zaina has the shape of the oval head rounded vs. almost triangular format of R. microlepidogaster; excluding the length of fins, differentiates this species for the same features that R. anitae has. Reproduction: The Rineloricaria species are usually cave spawners, where the female will place their eggs after the male has cleaned inside. The male will then guard and fan the eggs until hatching. The eggs will hatch in 4-5 days whereas the male can now be removed. More breeding information can be found here in the articles breeding section. Aquarium Care: As with all Rineloricaria provide long leaved plants or bamboo stalks for them to hang on to. Diet: Omnivore. Vegetable food such as cucumber and other various foods such as tablet, flake and frozen. Etymology: Local Brazilian name for the matte black or dark-brown fur of horses and cattle, referring to the dark-brown colour of some specimens and the dull, velvety appearance of their small odontodes. Remarks: More information in the referenced paper (Ghazzi, 2008).
