I am thinking about adding another fish or two my 180g DT. Currently, my tank is home to a large Purple Tang, large Kole, large-med Yellow Tang, 2 med Bartlett Anthias, 2 med-small True Percs, Scooter Blenny, and Purple Psuedo. Thats a total of nine fish, but the tangs are the decent size fish. I would love to add a Powder Blue Tang or Hippo Tang, but I think that would pushing my luck with the tangs. I would also love to add a Dwarf Angel or two, but I dont want to add anything that may damage any of corals. What do you guys think?
