Possible angelfish parasite

not sure if the other one posted, I don’t think it did but sorry if it did. My fish has been acting weird lately with swimming like it’s been having more trouble with going where the filter flow is and it swims a little to the side and one time I saw it upside down but than 2 seconds later it corrected itself. And than it’s ventrals in the front that hang down keep getting tangled together or vibrating. It also has black spots on the side of it on its scales but I’m not sure if those were there before because they might be normal. Yesterday I got super worried about a parasite because it pooped out a really green loop that looked like a thin yarn string when usually it’s poop is brown. It also took the fish like 30-45 mins to get its poop out which is a super long time. Thank you to anyone who responds and has any idea of what it could be. I really like my fish.
