Bluespotted cornetfish

This is a fish of many shapes and colors. Seen from the side they look skinny and long. From above they look much wider and, consequently, seem shorter. They look silvery from the side, green from above and they’ll add dark bars sometimes.

This one was hanging out in shallow water and showed no inclination to move on. It might have been guarding eggs, but that’s just speculation on my part. It shows a green tint and also the blue spots and lines that give it its name.

In my attempts to identify what I see in the water, I use John P. Hoover’s book The Ultimate Guide to Hawaiian Reef Fishes, Sea Turtles, Dolphins, Whales, and Seals. His website is hawaiisfishes.com.

Oval Chromis

These little fish can have quite different coloration. The silvery one to the right is a common sight. The one above is a male in his courtship and spawning colors. Later, when he’s guarding the eggs, he’ll be a more silvery blue with an orange patch on the lower jaw. Juveniles can vary from silvery blue to yellow.

Many other fish also have extensive color variations, which can make it difficult identifying individuals. Oval Chromis are one the larger family of damselfishes. While their colors and patterns vary quite a bit, they all have a similar ‘look,’ which, in this case, helped narrow down what I was looking at.

Scrawled filefish

Scrawled Filefish
This filefish is quite distinctive. It has a flattened body and long tail fin. Typically, it has a pale body with blue spots and scribbly lines, which is where it gets its name. It also has the ability to darken to a camouflage pattern, which is what this one was doing, though the blue lines are still visible. When sporting the camouflage pattern, they lie on the coral and blend in very well indeed.

It’s quite common to see this fish, usually in ones and twos, hanging almost stationary in the water, facing into the current or swells. Often they can be found hanging out in the same area for days in a row. Usually, when I approach, they drift away with minimal effort or noticeable movement. They’re quite large – up to two feet – and fun to see with their big eyes and dignified manner.

Reef fish

Many fish make the reef homeA great variety of fish make their home among the rocks and coral on the coast. From the bottom these are: two indo-pacific sergeants, a scrawled filefish, two or three whitebar surgeonfish, and in the background, a number of black triggerfish.

One of the pleasures of snorkeling here is that there’s always something to see and every day is different.

This little diamond-shaped fish is probably my favorite to see on the reef. The first time I saw one I thought it was a jellyfish, shimmering along with its long filaments wavering behind it. I got a little closer and realized it was actually an extraordinary fish.

The juvenile gives no hint of what it will look like as an adult. It grows to four feet in length, becomes stocky, loses the filaments entirely, and ends up looking like a nightclub bouncer.

It’s always a thrill to see one of these, its little tail thrashing back and forth, hauling the long filaments behind it as it putters through the water.

Keeltail needlefish

Keeltail NeedlefishWhen snorkeling, the tendency is to look down where numerous reef fish can be seen darting through rocks and coral. Needlefish, on the other hand, are surface swimmers and, as such, can be a little unnerving. Many times I’ve looked up and found myself in the midst of a shoal of needlefish, circling around me. At such times, I try not to think of Custer’s Last Stand.
