Yeah, tons of people have them in reef tanks. Weird, I chose the Potters tooI am so tempted by the dwarf angel, especially the Potter's. It's so beautiful! I figured it was something I could try later on, if I decide to roll the dice on adding one to a tank with a lot of coral. I've read a lot and it seems like the best answer as to their reef-safeness is that it "depends on the fish" haha
