I'm new to Polypterus, so I've only kept P.senegalus (Long Fin I think... Can't tell yet) so far. My addiction is getting bigger by the second and I want more!
Right now, I have my little 5 inch Albino Senegal. That's my first, and doing a trial with that one lol. If he gets big fat and happy, I'll be looking for an ornate next.
