update, the emerald crabs are eating the bubble algae, and also are knocking my corals around, today they knocked my trumpet off, thank god it fell up right, and also my mushies, can i use supper glue to hold them down? how long should i wait for it to dry? 6 line is not harassing any one yet, i have plans to remove him in place of a royal gramma. and i would like a goby or a blenny. what do you think?
