Ive begun to notice some pits form on the head of my yellow tang and her lateral line is showing. I'm quite confident it is lateral line disease but I've read all over for treatment plans and some of them are quite confusing. What I have been doing so far: - I did a 30% water change. Did not seem to make much difference. - Tried varying the diet even more(seaweed, marine flakes, pellets, frozen brine, freeze dried mysis shimp) - Added Stress Coat - her fins were beginning to look red. Stress Coat did not help. That was last week and her health has only worsen so now I'm at the point where I could catch her, put her in my 10 gallon hospital and use some strong medication but from what I've read you can't really medicate lateral line disease. I've also read about electrical current issues, I don't think my tank is not grounded, but how would you ground an acrylic tank and is that even a possible cause? I'm running out of ideas to help my Tang and I really hate to see her health decline. She's been eating anything that goes into the tank and her color has not faded but she's been rubbing up against the live rock and scrapping herself lately so it's starting to worry me that she'll get an infection if she continues. Any help would be much appreciated!
