4 years later, these little buggers are still around, they never went bonkers as they did with Ken's tank. So I notice there's a frag swap relatively close by in Brisbane, if anyone on the list (emphasis... on the list) is going to attend I can bring them.
Fair warning, the size is from about dime size to considerably less than dime size, aka "Is there even a coral on that plug?" size. (see picture). Also recently swapped over tanks so tank is going through a case of the uglies, so some algae may hop on between now and then.
Otherwise they'll probably just get donated to the swap proper.
