Target feeding seems to have worked
I gave each polyp a PE mysis shrimp last night and today they're open and looking pleased as can be! Thanks for the advice guys. In regards to the mantis, I did see the guy once (and only once), in a crevis in the rock beating a new burrow, pretty positive it's a mantis. That's assuming that the clicking is the same critter that was making the noise pre-tank tear down per my earlier story.
