I am wondering did I make the wrong purchase, I had naught a Zebra Swallowtail Angelfish and I am wondering if I had received one that maybe a bad addition to my tank. I am not sure if it is the angelfish or the low nutrients in my tank or even some rocks fell but some of my corals have trauma, I had 1 Zoa disappear, also my chalice coral has some trauma. My other corals look fine and I have not seen him nip nor any of my other fish, does anyone else have any experience they can share on this fish. Also the only invert to have an issue was my fromia starfish but my Nems and snails are good and my torch’s/hammers are good
