Hi. I have a new Duncan coral, it's seems to be doing well and all of my tank parameters are good, it's open all day but as soon as I feed my pair of de vinchi clowns it closes up. It's only ever one head that closes and then it opens again about an hour or so later.
Does anyone have any idea why it does this or is this normal behaviour. It's open all the rest of the time, is this how they eat?
Sorry if it's a stupid question I'm pretty new to reef tanks
