Which Angelfish would be better for my tank? I have a 120G SPS dominated tank. I am considering adding an angel and was originally interested in the Lamarck since they seem to be relatively inexpensive. Recently, I discovered they are considered "large" angelfish. After doing some research on reef-safe angelfish, it appears that Swallowtails are popular and smaller than other angelfish. Is this true? Does anyone have experience with one or both of these fish? Swallowtails are a much more expensive fish out of the two, but not sure if either would outgrow my tank.. Thanks so much!
