whats the maximum size difference i can have between polys and still have them in the same tank without having to worry too much

ex. can i keep a 3" poly wih a 6" poly
 
it depends on the species and the girth/thickness of each bichir
 
there is no definite answer. so as stated above.... it depends. it is safer to keep larger size difference upper jaw bichirs together than lower jaws. ie a 9" polli would prob be ok with a 4" delhezi but keeping with a 9" endli would be more risky. the only experience of cannibalism i have had is with my weeksii. she ate a 10" rope when she was 11" and a 8" senegal when she was 13". she has a big mouth. lol
 
i think you will find that that is not a question that has a definitive answer. Alot depends on species, tank size, decor, etc
 
how about a 3in sen with a 5in albino sen?
