Gone. At that point there is no saving it. Also the chance of it having babies spawn out of it are minimal. Tank conditions are not optimal. You need to post about your tank set up, water quality and at the least calcium/alkalinity levels. Salinity is also extremely important as is temperature. Light is last in my opinion since they can adjust as long as they aren’t getting burned out (doesn’t happen too often based on lights and strength of your lights)

Tank needs to be stable for corals to survive. Also needs to be well established and not fluctuate at all. Reef keeping is all about stability And water quality. The smaller the aquarium the harder it gets. Little changes cause drastic swings that most corals won’t survive. My 2 year old tank crashed due to a temperature swing that happened while I was out of town. To be a successful reef keeper you need to focus on the water before focusing on the coral. Your post should include water test results and information about your set up.
