How can I stop or prevent them from doing this? I don't want my fish to get swim bladder issues because they are constantly gulping air and bubbles at the top after feeding. I'm pretty sure it is not aeration related because they only do this after feeding.
I am feeding ~10-15 hikari lionhead mini pellets each time 2-4 times a day. My 3 goldfish are each 2.5 inches long (not including their tail).
