I would say the first 3 are fine, I would be cautious about the eel, and I would say no to the trigger. IMO, they do not belong on the reef. They are not there in the ocean, and they will break chunks off of your LR. I found a prize piece had a huge chunk off of it one night, and it was reduced to rubble when I returned from a trip. It was in the QT tank, so I just ordered some new LR, and I had to take him back.
