my yellow polyps were introduced to my tank weeks ago andwas fine the first week. Now ALL of the polyps are closed and have been for almost two weeks now! I have no close why they would suddenly retract. All the vitals on the tank are stable and within range. I moved the polyps from a lower part of the tank to a little higher to see if a light change would make a difference in thier activity, but so far I have not seen a difference. I noticed these really small rolly-polly-looking bugs that were crawling on the rock where the polyps are. Is is possible that they were stressing it or possibly killing??? should I still try to feed it mysis shrimp even though the yellow polyps are closed?
