About 2-3 weeks ago i had a water mishap where i thought i didnt have enough salt in my water, but it turns out my gauge was just stuck so after i finally got it right my clown died. about 2-3 days ago i noticed that one of my zoas came off the frag and moved down on the rock. I dont know if it did this on its own or if a snail moved it. at about the same time one of my frags was pushed off the rock and landed on the sand. I left it there because it just started to open up again for the first time since the salinity mishap. today i went to moved it to its original spot and it immediately fell off the frag. what should i do? re attach it? right now both of my zoa colonies (about 6-8 polyps) are just laying there loose.
