I have a pin tail fairy wrasse and sometimes it’ll put all its fins up and just do circles around my royal gramma, or follow it’s exact movement. Doesn’t do it lots just here and there, not sure if it’s an agressive behaviour, it never goes after the royal gramma but the royal gramma doesn’t seem to like it. Opens its mouth and swims towards the fairy wrasse but it’s not phased by it at all. Anyone else’s fairy wrasse do this and if so what is it?
