What do you mean by twitching? Can you post video to youtube and copy and paste link to here?
Please find the test kit and post your results on here, knowing your water parameters is crucial to fish's health.

I added 2 little Cory catfish 2 days ago, nothing looked wrong with them (plus I see my catfish do this before I looked online and someone said it was nothing but I am kind of worried.

Fish do scratch/ rub on objects occasionally, but if it happens every day, there is a problem. Regular rubbing on objects is normally caused by external protozoan infections or other types of external parasites.

Shine a torch on the fish at night after the lights have gone out and see if they have a gold/ yellow sheen on their body. If they do, they have velvet.

Look for cream, white or grey patches on their body. This would be an external protozoan infection like Costia, Chilodonella or Trichodina.

See if you can get some clear pictures of the fish that is rubbing.

How long has the fish been rubbing on things for?

No, not until we know what's wrong with the little guy.

Okay I’m gonna try getting a video, I don’t see him rubbing against anything. He just goes sides ways then back fairly quickly. He is a big bad cory
