Tank crashed on June 5, 2018. It was alive and well 7 years. Bird nest started bleaching, perhaps because light was weakening and needed replacing. The downward spiral went fast, within 3 hours all was lost. Lost a nice fat black ocellaris clown, about 3 years old, 2 yellow tail damsels, about 4 years old, and a 6 line wrasse less than a year old. RIP old nano, you were a good tank for quite a while.
