Something to keep in mind also, as you add livestock, especially frags
attached to LR
, you will inadvertently add more hitchhikers to your tank. Although the dusters very well could have been in that rock all along and just finally reappeared. I had a pocillopora that was a LR
hitchhiker reappear when I added MH
lighting after being gone for over a year 8O . It sounds like you are doing something right
If you've change the fish (or one has died), then whatever it was eating now has a chance.
Very true. All sorts of things will come and go w/ time. It's an ecosystem after all lol, best of luck.
