Looks to be two different species of synodontis, not featherfin, or cories, looks to be some sort of hybrids...
Can you get closer shots? Id say you can cross off decorus, polli white, multipunctatus, and lucipinnis.
So im down to a hybrid, robertsi, or grandiops for the second one not sure what cross the first one is, its dark like a erutpus but yet lacks the featherfins...
