I have been stuck out of town for several weeks on business. My wife called in a panic saying my clownfish has 2 patches of what lshe can only describe as think white threads on one side. The patches are each only maybe 1/8 inch across but consist of a number of small whaite thread looking 'strings' Since I will not be able to get home till next week sometime I can not see them and do not recognize what they might be from just that description. Does it riung a bell with anyone and if so what should I tell her to do. I cant dump copper in there as it is mostly a coral tank and I understand they might not survive. Any advice would be appreciated.
