Genus
Common name: Dartfish
Scientific name: Alionematichthys
Alionematichthys is a genus of fish within the family Microdesmidae, commonly known as dartfish due to their darting swimming motion. These small, elongated fish are characterized by their bright colors and distinctive dorsal fins. They are popular in the reef aquarium hobby for their peaceful nature and interesting behavior. Dartfish prefer sandy substrates where they can burrow and require a well-established tank with plenty of hiding places. They are generally hardy but can be shy, so they do best in a calm aquarium environment with non-aggressive tank mates.
