Missing Bichir?

[Octopie]

So my bichir has been missing for a couple of days now. I bought it on Thursday ad haven't seen it since Sunday. It's in a tall hexagon 35 Gal tank with a 2-3" Ruby Shark, a 4-5" Zig Zag Eel and a 7" Leopard Pleco. There are plenty of hiding spaces and I have already checked the filter, the hiding spots and raked the gravel...

Is it possible that my pleco or my eel ate my bichir? The bichir is the same size as the pleco. I've been feeding them at night, a combo of fish flakes a dried blood worms. Should I switch to live to see if it'll appear?

Thanks

Do you have a tight fitting lid? Have you checked behind the tank or stand?

He could have died and the pleco ate the body, i had a spiny eel who i thought was missing, i searched the whole tank and it turns out he was in a piece of driftwood, i would take everything out the tank and go through the substrate again.
