Duncan Coral Issues

[whatcaneyedo]

Although I've never had any problems with coral reacting to underwater epoxy I've heard several stories of people who have. Maybe do a water change and run some fresh carbon and see if that helps. I've had my duncan colony close up for a day or so at a time in the past after being handled too much so also try leaving it alone for a while.

Arent you concerned that your mantis is going to kill and eat all of your fish and shrimp?
