Companion for bichirs?

something large enough to avoid getting eaten by the bichirs, preferably African non-Rift lake.

I've kept a juvi oscar with an adult senegal without any problems

anything peaceful that isnt bite sized/


make sure the bichir is getting its share of food

Tankmates

(*note :to avoid agression do not have breeding pairs )

well ...
Mine have lived with Blood Parrots, Corys, Tiger Barbs, Severums, Gourami's, Oscars, Flower Horn, Cuban cichlid, Peacock eels, Loachs, 3 inch comets, Geophagus ....

My 150 has a couple bichirs along with silver dollars, peacock cichlis, jack dempseys, an oscar, compressiceps, Synodontis eupterus, tiretrack eel, and a few others. I would avoid angels, seen too many torn up my bichirs. They usually grab their top or bottom fin and run around with them until they give up and let them go. Then the angels are torn up pretty bad until they heal.
