I am considering setting up a Butterfly tank of 66 gallons. But only live rock with the fishes will be a bit drab for me as an SPS fan. I plan for: Chaetodon collare, miliaris and rafflesi in the first hand. Lunula, melannotus, mertensii, punctatofasciatus, tinkeri and rafflesi as the second choice. And maybe some others. 1 - 2 angels will also probably fit in as well as an "old" flavescens surgeon. 11 years in my tanks and looks like just imported but is a bit calmer. Around 10 Chromis acares is planned to pick up the particles from food that the missing corals cant take. Anyone having an idea of which corals would have the best chanses? Or if there are similar tanks i could read about.
