Today, about half way into my dive, I was joined by a large midnight parrotfish (almost 3 feet long). It was charging around, stopping occasionally for a bite to eat. A few minutes later, I noticed a smaller midnight parrotfish (about 2 feet long) swimming towards me. The big parrotfish chased the smaller one away. The smaller fish folded down its dorsal fin, to make a hasty retreat. Most likely they were both males, and the larger male is always dominant. In past years, we have seen several male/female pairs of midnight parrotfish, happily co-existing, but I don't recall ever seeing a pair of males before.
This photo is more realistic than the one in our book.
