So the one millepora I added a week or so ago seems to be doing well so far..Good polyp extension, flow, and the shade of it's color appear to be natural and in the same state of health as when I purchased it. This is a 5 gallon tank though so I want to be particularly careful. Should I go ahead and add a different species of Acropora and observe it's signs of health? Yes, the frags are very in nexpensibe to use as testers but wanted to hear what other had to say.
