Thank you to the people within this community who took time to comment and downvote my mistake when I placed 7 bettas in a 60 gallon aquarium.
As mentioned before, I moved the bettas immediately and take them to a fish store where they can sell them.
This is the one I kept in an 8 gallon aquarium. He is happy now.
Thank you all for your comments and DMs.
