They all look great. There are polyps sticking out of all of them all the time. Two of them just have little polyps that stick out of the end of the bumps and the other two are covered in polyps. I hope it re encrusts the part that got damaged. I doubt I will have algae on there. I havent had any algae in months, so hopefully it will stay clear and regrow ok. It's very cool stuff and I am enjoying watching it. Thanks again and thanks for the help everyone.
