I apologize for the graphic picture however you can see the white on his back area. This happened in 24hrs and was very upsetting to see him go like this. My cowfish is in a hospital tank I made for him and treating him with blue but my lavender tang keeps showing up with white spots. I've been doaing the whole tank with melafix but that's just ******* all the coral and anemones off. I'm gonna do a 30 gallon water change today and keep on feeding like I have been with garlic, fuel (amino acids) and mysis . I will add the vitamin c today. Any other ideas, this is really a bummer . I thought about taking the whole tank apart .
