Okay lets try and figure out exactly what type she is. chances are she is one of the top three on the list below which one describes her most?
Most common ones sold in lfs are:
Delhezi:The upper surface is greyish, with hints of green or yellowish colouration. The ventral surface is a uniform lighter colour. There are 7-8 dark vertical bands which vary in thickness between individuals. 10-13 dorsal finlets. The mouth is relatively small for the fish's size.
Senegalus: Uniform brownish-grey to olive colour on dorsal surface, ventral surface whitish. No banding on adults, very young juveniles show three horizontal bands. Upper jaw slightly longer than lower jaw. 8-11 dorsal finlets.
Ornate:The striking black and yellow patterning of this species extends into the fins, making for a very attractively patterned bichir. The head has a finely reticulated pattern. 9-11 dorsal spines present
Endlicheri:Colour can be yellowish-brown to grey. There are several dark vertical bands. Black spots are often present on the head region. The lower jaw is more prominent, extending beyond the upper jaw. Dorsal spines extend forward to the rear of the pectoral fins.
Weeksii :This species usually has a very clear distinction between the dark greyish-green dorsal surface and the whitish ventral surface. Several dark bands are present which may fork towards the bottom. The head is relatively large, giving rise to one of the common names of 'fat-headed' bichir. This species retains external gills much longer than most other Polypterus species. There are 9-11 dorsal finlets.
Lapradei: Grey to greenish-grey colouration, with a paler ventral surface. Horizontal bands evident on the upper surface from the head to the dorsal finlets, and extending about halfway along the side of the body from behind the gills. The flanks have irregular vertical bands. Prominent lower jaw longer than upper jaw. 13-17 dorsal spines.
