Neon Green Darter Characin

One of the more unusual so-called “darter tetras” known to the hobby, the Neon Green Darter Characin inhabits the middle and lower Rio Negro in Brazil where it is typically found in shallow, fast-flowing streams and minor tributaries, often in clear water. Their unusual body shape is uniquely adapted for life among submerged root systems and tangles of aquatic or terrestrial vegetation in moderate to strong current. This species, the only member of its genus, is named for the brilliant iridescent green coloration it typically displays when comfortable but it is capable of a remarkable range of color change in response to both its surroundings and mood, and keeping these Characins in a planted aquarium may help them display their best colors. An agile micropredator, the Neon Green Darter Characin feeds on tiny invertebrates in the wild and will appreciate small live foods like baby brine shrimp or white worms in the aquarium. They will typically learn to feed on small frozen foods but a varied diet is best, and tankmates should be chosen with care so they don’t outcompete the darters for food. A fascinating and colorful centerpiece fish for a species or biotope themed aquarium, they are a social species and should be kept in groups.
