Out of the blue, my yellow tang seems to be developing the lateral line disease. I started noticing that his fins looked "nipped" about 2-3 weeks ago, and heard that sometimes broccoli can help with that, so they've all been eating that along with Rod's and Mysis. I've also started feeding more seaweed strips as well. But today I noticed that it now has these red looking legions on it's top fin and tail area... Doesn't look good. From my tests, my water quality is fine. So it's just a vitamin or "greens" thing? I also saw that sometimes electricity leaking in can cause it? I've never tested for that, I'm just assuming that everything is grounded and there's no stray voltage or anything. Is it reversible?
