Is the any of the Birdsnest touching anything? 4 days ago I had a pink Birdnest I was rather proud of cuz it tripled in size of 5 months. There was one point touching a green Velvet Musroom. That little tip turned white and I figured it wasnt much to worry about but for a week 99% of it remained beautifully healthy with purple polyps out constantly.

4 days ago I changed my Chemi-Pure, Pura and Poly filters. the next mornng the bleaching spread from that tip to like 20% of the colony. I moved it immediately but it was too late. Two days later it was completely bleached.

I later learned that Green Velvet Mushrooms are a type of Anenome with its own supply to vemon and I guess the suddenly improved, clear as hell water from the new medias made the sting stronger. Or it could be coincidnece. So lesson learned the hard way. Most of my speciemns will never touch again.

Good Luck with yours.
