Hi! I’ve bought a few clippings of corals off of a local reefer which I temporarily “parked” in my nano tank until my larger tank is mature enough. All of them are doing well and I’ve spotted new growth on them. However, the one in the attached picture is bleaching at the bottom. It’s been like this for a while and hard to determine if it’s moving up. I have a similar one in a different color which is parked right next to it and is doing fine. Does anyone know what is causing the bleaching? Also… what is the name of this coral? Thanks!
