hi
I would say yes. I never kept my marulioides with a bichir, but lots of other fish. The thing about marulioides is that it isnt very aggressive unless something (like a CA-cichlid) is giving him a hard time. Then he will kick the s*** out of the poor bastard.
Calm, non-aggressive fish on the other hand was never a problem for me. I kept him most of the time with a clarias cat and a sailfin pleco. Ofcourse their fins where maybe a bit torn sometimes (not often), but on the whole it worked out fine.
And since bichirs arent aggressive, I dont think it will be a problem.
(sorry for my bad english)
