Fishy Friday and Flashback Friday in one: the Moorish idol or the black and white butterfly fish. Photography challenge Day 75

Today’s photograph is also another flashback Friday photo for my trip to Hawaii. One of the things I tried to do on my trip was sit near the water in areas where I could observe fish and other aquatic life. I then tried to zoom in with my camera to get pictures (this was all before I got a digital camera that I could then actually put in the water). So some of the photos came out nice and crisp, and other (like this one) had more of abstract look to them.

It’s either the Moorish idol or a black and white butterflyfish

I thought that the fish in the photo is the Moorish idol (Zanclus cornutus)—or a member of the butterfly fishes that also closely resembles it—hard to totally tell from the picture. Anyway—the Moorish idol is a fish that has a wide distribution through the tropical and subtropical waters, especially around reefs and lagoons. But know I think that it is the black and white butterflyfish; these fish are also found throughout the tropical and subtropical waters around reefs.

The diet of the butterfly fish varies depending on the species—some eat coral polyps and sea anemones, while others are more omnivorous (which makes them easier to care for in salt water aquariums).

The way the fish mature is unique as well—butterfly fish release their eggs, which float on the currents with plankton until hatching. Then as they mature, the young go through a stage where they are covered in large, bony plates that are shed when they mature.

The Moorish idol is a very difficult fish to try to keep in captivity—mainly due to its diet (it feasts on sponges, coral polyps, tunicates, and various other invertebrates) and the fact that they require very large tanks as well. So that is why butterflyfishes (especially the black and white) are sometimes called the Moorish idol replacements.

I would like to go back to Hawaii and try my hand again at getting pictures of various fish under water, now that I do have a camera that I can stick underwater (at least a few feet).

Photography Challenge Day 61: Fishy Friday and Flashback Friday in one: The Unicorn Fish swimming in the aquarium at the Mokupapapa Discovery Center in Hilo, Hawaii

So today’s FishyFriday post is the “unicorn fish” and also a Flashback Friday post to my one trip to Hawaii (namely the big island).

Unicorn Fish swimming in the aquarium at the Mokupapapa Discovery Center

It has been almost ten years since I went to Hawaii (I went in December 2009 to celebrate having passed my dissertation proposal exam—which meant I was basically one presentation/paper away from getting my PhD). I managed to pack quite a bit of sightseeing of the large island in during that time—especially seeing the Volcano National Park twice.

I spent quite a bit of time walking in Hilo, and one of the stops was the Mokupapapa Discovery Center, which focuses on the native coral reefs and fish around Hawaii. Within the Discovery Center is a 3,500-gallon saltwater aquarium with numerous different fish.

One of those fish is the “unicorn fish”. There are twenty species, and they are found in the Indo-Pacific region of the oceans. They get their name from the long spike that is protruding from the forehead.

These fish are herbivores feeding on algae (though they can also be opportunistic feeders and eat other small invertebrates that they come across as well), and travel in groups (called schools).

One of the things I would like to do is get back to Hawaii for another visit. There are other areas of the Big Island I would like to see, and I would to see how Mother Nature changed the landscape of the Volcano National Park as well.
