my bichir is with a bunch of cherry barbs, zebra danios, rainbow sharks, and such. Itry to keep him well fed and nothing has gone missing yet except 1 danio, but that was day 1 of them being in the same tank. I think your corys will go missing though, mine always do~
keep them apart if you can, together if its your only choice but prepare to see some things with a bite or gone.
