Any loaches that can live with aggressive cichlids and large

 
Any loaches that can live with aggressive cichlids and large bichirs?
Alright I got a 5.5 inch convict, an aggressive 6.5 inch severum, a 8 inch senegal bichir, and a 6 inch ornate bichir. Are there any species of loaches that can survive with that?
Tank size?

Adult clown loaches are able to look after themselves with similar sized cichlids, but a group of large clowns needs a LOT of space (100+gallons).

Smaller ones are likely to be bullied by the cichlids, or swallowed by the bichir.
