I’ve been able to add a few corals to my little diy nano tank over the last month or so and everything seems to be going well. One of my corals is a Duncan with over 10 heads which spreads out great, but retracts every time a fish either bumps it or even gets close. Takes 10-15 min to open up and then it happens all over again. My question is, in your experience, do they ever get used to fish being around them? Just a curious newbie!
