Foureye Butterflyfish in Cozumel, July 19, 2021

A tropical fish that I enjoy watching is the Foureye Butterflyfish since they are often in pairs. The Florida Museum website tells us, “This is one of the few fish that seems to mate for life.”

The website continues to say,

Male and female foureye butterflies form pairs early in life. These pairs can be long lasting, suggesting that a monogamous relationship may exist between the pair members. If the two fish get separated, one partner will swim upward for a better view in an effort to rejoin the other partner. Courtship between the two is prolonged and energetic. Often the fish will circle each other, head to tail, until one fish breaks and runs, with the other close behind. They will chase each other all about the reef, and chase away any lone foureye that approaches them. Actual spawning takes place at dusk. The female releases from 3000 to 4000 eggs a night. The eggs are small, pelagic, and hatch within a day.

Although the fish are beautiful, take a look at how healthy the coral is that they are swimming near! After seeing so many diseased and dead coral in Florida, healthy coral is a welcomed sight. Although coral identification can be a challenge for me, based on the star coral identification page on the scubadiverslife.com website, I think we are seeing Mountainous Star Coral and Lettuce Coral.
