May or may not be an emergency but better safe than sorry. Added my pair of clownfish one week ago. Added my royal gramma about a month before. Royal gramma is 1 1/4 times the size of the clownfish and the clownfish won’t stop pestering the royal gramma. They have been great with each other for the last week but now the gramma is starting to defend its territory and opening its mouth at the clownfish when it comes near. Royal gramma hasn’t bitten yet but has gotten right next to him. As I’m writing this, they’re both starting to bug him. What should I do? Separate or let them do their thing and settle it out?
