questions for the zoa experts

[lastlight]

for the record my zoas are all doing really well with a couple exceptions.

1. first up are my candy apple redds. these have exploded in growth and have always been in the same spot. gradually their red has darkened to the point where they are mostly just green palys now. when my tank was having sps issues i reduced my light output from 80% down to 60% and have been very slowly bringing it back up. I'm at 70% currently. Could lighting intensity be to blame?

2. my god of wars have also grown very well and continue to do so. but about 8 polyps of the total 30 or so have gone umbrella shaped. they curl downwards. any ideas? these polyps as well as the normal looking ones all have great colour.

thanks!
