i have three small frags of Xiena and about 2 weeks ago one of them closed and has not opened it could be from something else but the other two are doing fine and just recently i have noticed my flame angel nipping on them every time he is near the rock but its just one nip so i guess they get nipped at least twice a day or sometimes when i see not at all .... is this a big deal or not cuz after he nips it opens up again (that polyp)
so is a big deal can i leave everything the way it is with them still surviving .. like can they live like this?
