The Bucktooth Tetra (Exodon paradoxus) is sort of a misnomer in that this fish isn't buck toothed at all. It does however eat the scales of other fish species. Caution is advised if you plan on stocking them with fish that have scales. They reportedly do fine with catfish species. They need to be kept in schools of 5 to 7 or more for best results.
They are considered quite hardy once established and fed a good quality flake or pellet food. Several small feedings per day are recommended.
The Bucktooth Tetra gets to be about 2.9 inches (7.5 cm).

Blind Cave Tetra
The Blind Cave tetras live in deep caves in the wild. They range from Texas to Mexico, with the sighted version from Mexico to Panama. There is no need for eye sight in the pitch black caves, so they have evolved to adapt to these conditions.
