Hello All! My new bta has been in my tank for 4 days now and it appeared ok for the first 2 or 3 days, but today it's not looking too hot. It has these big white lips, around its mouth and there is pinkish purple stuff coming out of it. I hope it's not zooxanthellae If someone could help me out, I included some pics of the white lips, stringy tentacles, and pinkish purple stuff.
