I have a 125 with (2) 8-10" Ornate bichir eels. Anyone have any luck mixing other types of bichirs together. Is the tank big enough? There are lots of rocks and hiding places and I am getting the plants going in there. Talk to me.
People mix the different Polypterus species all the time, you just want to be careful with size difference. Other than that I'm not aware of any Poly's that need to be keep separate.
