Are Dinosaur Bichirs Solitary Fish?

Your bichirs are beautiful. .

Thanks! The one up front is wild caught which would explain his head shape

no studies have concluded as to whether they're solitary in the wild. however, in my limited experience, they have no problems co-habiting with a large number of their fellow polys in a reasonably sized tank (in fact, they do develop some sort of a pack hierarchy).
