Hello,
from your point of view i'm keeping two "rare" species: Polypterus weeksi and Polypterus teugelsi.
Indeed - P.weeksi isn't that rare species as teugelsi is ... but it's also a fact of where you are living. I think Arkansas isn't a "Poly-paradise" ... the same situation as in Germany. Here P.weeksi IS a rare fish!
My weeksi is about 6'' long and still has his well-developed external gills. Although he comes to the surface to breathe. Weeksi has the ability to feed fish which are half as long as he is ...
Weeksi has a remarkable head; i think adult individuals are real predators in the style of adult P.ornatipinnis.
The coloration is different from individual to individual - there are almost uni-coloured fishes as there are rich coloured fishes, these are looking superficially a bit like delhezi.
Weeksi is not that wonder of growing-up like ornatipinnis, and he is definitely no action-hero.
On the other side P.teugelsi ... action-hero extravaganza! He's my most active Polypterus - and my most aggressive. He snaps after all other tankmates but didn't hurt them. I don't know if this behaviour is territorial (i think so) or caused by an enormous appetite (he has an enormous appetite but i don't think he is seeing his tankmates as prey).
P.teugelsi came the first time to Germany last year imported by Andreas Lorenz,
www.tropicfish.de - Aquarium Glaser, who is also dealing in the USA and Japan, affirmed this first-time-import, but i'm sure he was second ...
Ralf Britz, who described P.teugelsi the first time, didn't know that teugelsi is one ofe the longest Polypterus species ... mine is about 18'' long but i have seen a pic (my dealer had sent it to me) of a teugelsi about 25'' long! Remember: Men have not seen many teugelsi until this time ... remember the "fact", that P.ansorgii is one of the smallest bichirs (brave statement when knowing only 3 individuals in alcohol!).
I could write many more about P.teugelsi and P.weeksi ... but there are so many facts, so many observations ... it's better to ask me.
The pictures: I will make some pics the next days.
