I bought I rock flower anemone two weeks ago, was doing great until about 4 days ago when his mouth was wide open and not closing. After a few days he was shriveled up lack of color and mouth still wide open. I don’t know what to do he’s not happy and he looks very sick. Could this be happening because of my BTA they haven’t come in contact yet but it’s still a interest any info will help will repost with a pic.
