Species Information
Size	82mm or 3.2" SL. Find near, nearer or same sized spp.
Identification	Hoplosternum punctatum and Dianema longibarbis is sometimes confused. Hoplosternum punctatum has smaller eyes and the eye is just a little above the exact center of the side, see this image; D. longibarbis has large eyes which are placed exactly on the sides, sometimes even a bit on the lower half. See this image and this image. In adults differences in bodyshape and armor are easier to spot; the pectoral shields in Hoplosternum punctatum leave a space in the center (females) or overlap (males), but in Dianema these are closely fitted together. Within the genus of Dianema: D. longibarbis Clear tail fin, the only other member of the genus has horizontal black and white alternating stripes on the caudal fin and is generally larger.
Sexing	Females are larger than males but the difference is slight.
