Ok so , I heard the angel is a hit or miss and I am willing to take that risk haha , and I know the harlequin tusk is very reef safe but not invert safe and that's why I am going to add him ,because my tank has no inverts , and my tank is very peaceful so he will be the most aggressive fish and last fish to add , I am purchasing him as small as 1 inch and I am adding him to my 60 gallon reef/ no inverts , I also have tiny baby tangs and anthias , and when they out grow it , I'm getting a 300 gallon haha
