Quick Overview
The blind tetra (Astyanax mexicanus) is a unique species native to the caves of Mexico, where it evolved in complete darkness. Lacking eyes and pigmentation, it relies on a highly developed lateral line to navigate its environment. This schooling fish thrives in groups and coexists well with other peaceful species. Hardy and adaptable, it tolerates a wide range of water conditions, making it an excellent choice for beginner aquarists. A varied diet and a well-structured tank will help ensure its health and vitality.
