Rays with Catfish - Your Opinion

I have been looking for something that will help with cleanup after feeding. I use to have a few fish for the job, buy over the years have either lost them to age or to momma ray deciding she wanted a snack. So I have been trying to find large enough tin foil barbs or silver dollars to do the job, but not had any luck in finding the size I need.
I decided to try out a catfish. I found a 2" RTC/Shovel Nose hybrid catfish yesterday. So far, everything is ok but he is still new.
I have always lived by the idea that a ray tank should not have catfish or sucker fish in there. I know others do it and don't have problems, but I just never wanted to do it.
But I broke down and decided to try a catfish.

My tank has 2 Motoro rays, 1 large Dat, 4 Large Clown Loaches, 1 Florida Gar and 3 P-Bass. And now this Catfish.

What do you guys who have catfish think? What have you had issues with when keeping a catfish if any?
Of if you don't keep catfish, is there a reason why you don't? (besides the fact you have never bought one)

ya, my rays do a good job of eating and everything in the tank eats the same stuff. But from time to time (ever since my bala shark and silver dollars are gone), I find larger pieces that might have fallen behind the driftwood were the rays can get into. Then I have a few shreds here and there. Just want something that will help clean this up. By Loaches do ok at cleaning up the shreds, but not always. Still wanting some Tin Foil Bards though. Red tail Tin Foils.

I pulled all my driftwood and just left a few large rocks. Just to give space and keep my large ATF and future Armatus from damaging themselves.
I know the only tin foils I see up around St. Louis area are standard Tin Foils. I do see large Silver Dollars more often on occassions.

Ya, not down here in Springfield. Cant find anyone around that has any large enough.

Well his size wont be a problem. We have a large enough tank right now and in the process of building a indoor pond, so not so worried about that.
Well, as I said before , Im still looking for large enough tin foil barbs to use for a clean up crew. Hoping at least this RTC/SN hybrid helps get the bigger pieces the rays wont/don't eat. All my other fish will not eat off the bottom except the gar, so whatever hits the bottom, the rays need to eat or hoping the catfish does as well.
