Are these the size of the frags you bought ?
Or are they what you've fragged off from the frags you got to try save the piece of sps that not stn/rtn?
When I see threads like this I get that people say it's new tank and could be pests and what not,buy often think is it because size of frags that we often buy and they so dang small and just recently cut at the lfs before we buy ( can often see gleaming white plugs with no algae growth or corals entrusting ) and think with just being cut/fragged and it so small and going from lfs system to ours and lights/flow/parameters different then the tiny incy windy frags just not strong enough to cope .
.as I say just what I wonder,don't know if true or not
