Can I mix any of these fish with Discus?

Hey Everybody,

I'm thinking of puting some discus in a 4x2x2 but I was also wondering whether any of these fish would be compatible :

Albino Senegalus ( these guys are fairies )
L168
L104
A Banjo Catfish
Leporacanthicus Triactis (he's only little atm but I figure he might grow up and harass them )
Perhaps some Hypancistrus sp.
Perhaps some Whiptail sp.

I figure the Polypterus and Three Beacon Pleco could be aggressive toward them but I'm thinking the rest would probably be ok?

I'd also be interested in what you guys are keeping with your Discus or whether you strictly keep in species tanks.

Thanks James

not sure how much help I'm being but whiptails are fine with discus, I've had 1 that had a bit of a taste for discus slime, but they're so clumsy the discus easilly get away and often respond with a quick nip to his tail
