It was in the LFS tank for about three months. When I got it, it was white w/ purple tips. After a while it turned that non/off white, which I was told that would go back to white after it got used to my lights. I have had it for about a month or so. I have fed it twice since I have had it, about once every 2 weeks. What could of caused this? I do have 2 peppermint shrimp. LMK if you guys need any other info. Within a few days of me bringing it home. Yesterday it was fine, then today it looks like this. Edit: Added a pic.
