It looks like a prolapse. From the apparent age of the fish, I'm going to guess an anal prolapse. The large fins and coloration suggests it's just passing into sexual maturity so I'm guessing it's not more than 4" long, give or take, so it's not likely to be a prolapsed vent. Please confirm the size of the fish to ensure my observations are on target.Yeah i looked it up and it looked pretty similar thank you for your help
I've never had to treat a prolapse. Success stories that I've read discussed soaking the fish's foods in epsom salts and adding epsom salts to the water. This would be better if you had a smaller quarantine tank to put the fish in during treatment. For exact dosages, I'm going to suggest you do an internet search for "cichlid anal prolapse treatment" and read several articles and maybe watch a few videos and proceed with the dosages that appeared to give the best success.
