No matter how well you prepare, when you do water change, your tank water temperature always drops, thus, causes the fish to vomit the food. For the same reason, sometimes, fish doesn't eat well, if you feed them right after doing water change. I always feed a day before or after the day that I do water change.
 
I have to agree ^^.
 
When it's w/c day, I feed my fish then change the water about 20mins later. I've never had a problem arise..............
 
I don't feed on WC day, I've same problem like some members already said that their catfish would vomit out its meal after WC done.
Edit:
If it vomited then it wouldn't eat again a week later.....

I feed before a water change...hours after. I give the fish time to digest.
I agree with this......90% of the time regurgitations in ANY ectotherm are due to temperatures , the other 10% is stress or pathogens. I always refill w/ water slightly warmer than the tank and NEVER cooler. Lower temps will almost always cause regurge. However, I still do pellets and flakes on WC days, and I have never had a fish regurge in my life
