Can you put a Powder Blue Jack Dempsey with Corydora Catfish in the same

[MARIA]

fish tank -- 65 gallons? I have a Powder Blue Jack Dempsey with Angelfish in the same tank, and they all get along perfect. I was nervous about introducing them, but the powder blue jack dempsey has never shown any type of aggression towards the angelfish. I got a Raphael catfish to scavange around (mostly because they have pretty tough armour), but he hasn't really been eating much of the leftover food. I'm afraid that the tank is getting dirty, so I'm considering getting some corydora to help out.

I know these species are peaceful towards all species, but I'm unsure if they're compatible with the blue jack dempsey. Are they? If not, how about Pictus Catfish? Are they good scavangers? I've had them before, but they seemed to prefer rushing to eat food on the top of the tank rather than in the bottom.

If neither of these fish work, what type of catfish should I try to get? Thanks!
I make sure to feed the fish just as much as they can eat in two minutes, no more or less. Sometimes I even hand-feed them so no food goes in the bottom of the tank, and when the lights are out I put hikari sinking algae pellets for the catfish... even then, I noticed some debris in the gravel when I did a water change. What species of catfish do you suggest?

the Jack D's will be nudging the Cory's around anyway, and if they spawn, that may be doom for Cory's... the JD spawn will be on bottom, and near the Cory's food zone

and...as Big Gourami pointed out, the spines of a 1 inch Cory stick into the mouth of the JD's and the Cory will drown, while you get to use needle-nosed pliers or long hemo's to remove the Cory, or else JD dies too

....otherwise the scales and points of a Cory are very durable and an effective means of surviving the nipping and nudging of predators...while the Cory's are so peaceful
...i like a group of Cory's 8-12, they're happy together
