Hi fellow MFKers, I hope that someone can help me. I'm trying to figure out what exactly the differences between the Polli and Senegal bichirs. I've read the sticky and looked at pictures but they look the same to me. The reason that I ask is because the lfs that I work at has a small Polli for $19. I already have a Senegal, which I love, but don't really want to spend 3x the price on a "duplicate". Any help would be greatly appreciated & thanks again.
