Hi, I am new to reefing, and just started my tank in September 2020. I got my first two fish a couple days after the tank was running. They are a Black Ice clownfish pair. They both are really active until about a week ago (month two of them being in the tank) the female started eating less. She does eat but looks like she has a hard time doing it. I then noticed white stringy poop coming out of her? A few days later she won’t leave one side of the tank and there is a red mark on her face with white bumps? This is when I got worried. A day later a big bulge was on her side. I suspected she hit a rock or something but realized it was kind of unluckily. A week later (today) the red mark is completely white, and the bulge got pointy and dark and when I went to look at it again today it looks like a big hole with something inside of it? It looks like the inside of a tan tan when Han Solo cut it open in Star Wars.
Does anyone know what it is and how to treat it? Thank you! Picture below.
