My PE isnt very evident in the day at all, but its not a problem for SPS. In the wild, SPS colonies keep their polyps locked up during the day too, so its completely natural for them to do so. Somewhere along the line, it was "deemed" that SPS that had huge hairy bushy polyps were healthy, and if they didnt, they werent. Just aint true. Also, naturally, the more you feed, the less likely theyll pick, but IMO, it is a force that cant be stopped. Coral slime is tasty.
