A synodontis and a german blue ram, with the "balloon" deformity. You should return them ASAP if you can't get a 20g tank or larger for them, keeping fish in bowls (especially larger active fish like synodontis) is a bad idea. If left in there any longer they'll die of the ammonia they're producing (and as they produce more when they're stressed, like they'd be in a tiny bowl with nothing to hide in, there's probably a lot of ammonia in there).
