So I have a 6” undulated triggerfish. I added a 3” undulated about 2 months ago and everyone said I was crazy putting them in the same tank. Well they were both the same color for the first month and a half. Well two weeks ago I noticed the smaller one changed from green blue and orange to green purple and orange. Then never attack each other and now I see them doing the twitchy “dance” that clownfish do when they pair. So my question is are they bonding?
