looks like a prolapse
the reddening near the anus is more of a concern. I suspect could also be at the very least contributing to the issue..thiis may have to run it's course ..I'm not sure there is much you can do for a prolapse.
they can be caused by any number of things..constipation, infection(bacterial or parasitic).. I lost an angel many years ago from a camallanus infection.. the parasites were taken care of with meds, but the fish could not pass the parasite eventually leading to a bacterial infection..
