thanks davo! you mean behavior? there seem to be some generalization to some extent, eg. senegalus and palmas polli are usually very outgoing and active, delhezi is semi-active, and palmas polli tend to get fat. the protruding lower jaw and upper jaw species might have different feeding habits due to the difference in the shape of their jaws, although that probably shows up only when feeding live food. the rest of the bichir species are generally quite nocturnal. P.bichir lapradei are generally shy, P. endli endli are generally lazy (although i have an exception), whereas P. endli congicus is actually semi-active ime. But these are just generalization, there are always individual exception.
anyway, thats probably more than what you asked for LOL, i haven't observed any distinct behavior from the ansorgii. the one thing that makes it stand out is its unique patterns, two rows of squarish to rectangular-ish blotches on the side and back.
