So two of my catfish have died for unknown reasons, I’m pretty sure it was lack of food or something. I have 6 in my tank right now. I have one betta in there and I think he eats my catfish’s food so I feed them at night while betta is less active. I feed them sinking carnivore pellets (Please recommend me other food suggestions for my catfish (and betta too!). I do a water change 25% every 2 weeks. I got a 20 gallon long.

What are your ammonia, nitrite and nitrate levels?
Do a 75% water change.

Lack of food is a less likely cause of the cory catfish deaths. Keep an eye on the Betta, he may have decided "his" space no longer has a welcome mat for the catfish. It has happened with others.
To the food for cories...Omega One Shrimp Pellets, Fluval Bug Bites. Nutrafin also make a tab with earthworm. These brands I specifically name because they are hgher quality (the last perhaps less so, but one out of three is not too bad). If you live in the UK there is a tablet food specifically made for catfish, but I cannot remember the name. From what I have been told it is similar to the Nutrafin. Ian Fuller the Corydoras authority was consulted on the manufacture so it will be good.
Corydoras' prime natural food is insect larvae which they filter feed from the substrate. This is why the Bug Bites are so good. They initially float and upper fish will readily eat them, so the Betta will love these too, and you can feed them well after dark so they get down to the cories. By well after dark I mean an hour after the room is pitch dark. Fish do not "sleep" when the tank light is off if there is still ambient light in the room, so it has to be total darkness. Cories are nocturnal and will be out scampering about in pitch black, but not a Betta.
Other foods for cories are frozen daphnia and frozen bloodworms, the latter no more often than once a week. The Betta will likely go after these too, which is OK but make sure some get to the substrate.

Betta are not community fish, they have a type A personality to the extreme. They do not get along with their own kind and do not even like their own females except for a short period during breeding and then they may even kill their mate. I would separate your Betta from the other fish. A good tank mate for Betta are snails. That said you still need to check the quality of your water to see if there is any ammonia. Do you have a water test kit?

yes, I checked it seems to be normal, I do have a algea problem though.
I've had them for a year when they died, the tank was setup for a year. I clean the filter like every 3 weeks, the catfish looked white but it was torn up, no way the betta killed it cuz they were like kinda large.
yeah I seen those bug bites I really want to get some!
I have had a betta kill a 5 inch kuhli loach. 2 of them actually.... they can be vicious. And for months it can be fine but one day he may just switch and kill all the fish in the tank
I had this betta for a while, he just ignores the catfish plus I don't think he would bother them together in a group.
I wont argue, just be cautious. I thought the same with my 8 kuhli loaches but he liked 2 after a full year living peacefully
Occams razor. The answer with the least amount of assumptions is the most likely.
In this case the betta killing your other fish is the answer with the least assumptions.
Yup will be
