my 29 is 7 months old. my qt tank was about 3 months old.
the spots are hard to see in the pic. they almost looked like the parasite that attacks clams but I spoke to someone at my LFS
and he told me there isn't any parasites that attack Acans. Well right now I think the Acans are a total loss!
they're completely white, receded, and I see no way that there still alive. only time will tell i guess.
