So I have had a solar flare Acro frag for a couple weeks now. It was doing fine for the first week but now it’s beginning to have much less polyp extension and color loss. I tested all levels and they seemed alright but Today I noticed a small white bug crawling on my Acro. It had a weird trunk kinda like a nassarius snail. Can anyone tell me what it is and how to kill it? No signs of necrosis yet
