Black Moore goldfish

Hello everyone,
I'm having some problems with my black Moore goldfish, ever since we got him around 3 months ago he or she has been swimming upside down 70% of the time, I can help sometimes with giving him fibre in some spinach or beans as I figured it might be the common problem with constipation or too much air in him but that didn't seem to help today and he cannot stop swimming upside down and floating around lifelessly. I wonder what I can do to make him better as we have a second black Moore goldfish in the same tank who is no problem and completely fine.
