They are very clumsy fish that (in my own experience) are more often than not hiding. They can and will eat any fish that will fit in their mouths. They can be hard to feed with other fish in the tank, my bichirs have always been the last to get to food; they rely heavily on their sense of smell to find it and aren't too good at immediately darting to it. Senegals get to about a foot long and would require about a 55g tank, I believe the P. delhezi I have will get to about a foot and a half; he's in a 75g. Overall they are very interesting fish, hardy too. They gulp air from the surface and are very forgiving about water chemistry (I'm not suggesting that you test this though )
i named the senegal bichir cuddles... he has a really adorable face...and the dinosaur like spines on his back make the name quite ironic XD My plan is to get a very large aquarium and probably put an Oscar, Zebra Shovelnose Catfish, and Bichir in it, but that'll be in a couple of years 
Also, which type of Bichir is the smallest? Also, why do the larger lower jaw species require a wider tank then the larger upper jaw species? And originally I had been looking for information on their personalities and just some stories of some quirky things their own Bichirs have done, and some cute things and stories, etc. But anything works, really. I'm open to any information you can give me lol
That's a lot of good information, thank you!
