I have anchor moss in my tank but it's not doing too well, I put this down to my neglect of my aquariums recently, university has been busy. It is a lovely moss though and it appears to be really easy to grow emersed too which I am doing hopefully to re-build the amount of moss to work with in the future.
I think with most mosses they do prefer cooler temperatures and I found at least with Java moss, that they do appreciate some flow into them to get rid of debris along side with shrimps. At water changes, use your hands to gently brush the moss and siphon the debris too will help.
