Trifasciatus Pencilfish (Nannostomus trifasciatus) – Group of 5 Fish


The Trifasciatus or Three Lined Pencilfish is a colorful, small-growing characin found throughout much of the Amazon basin and Guyana shield. In the wild, these fish inhabit areas of warm, acidic, slow-moving water, typically in large groups alongside tetras or other small schooling fish. They are well-suited for a peaceful community aquarium and are popular with aquascapers and planted tank hobbyists due to their color and interesting behavior. With their small adult size, they also make a great fish for nano aquariums as well. This species is hardy and will thrive in a variety of setups, but care should be taken to ensure larger or faster moving tankmates don’t outcompete them for food.
