The Bicolor Angelfish, also spelled Bicolour Angelfish (Centropyge bicolor), is a small species of angelfish seen in both Endless Ocean and Endless Ocean 2.

It is named for the striking contrast between the yellow front half of its body and the dark-blue back half, with a bold yellow tail fin. Bicolor angelfish are frequently seen in small groups, but can also be found alone or in pairs.

Endless Ocean

Description

"These fish have narrow, elliptical bodies that are bright yellow and blue in color. They can be seen year-round at reefs all over Manoa Lai.

There are spines just below the gills that face backward, which is one of the most distinctive features of the family Pomacanthidae--of which these fish are a part. Males usually live together in rocky or coral reefs with multiple females.

If there are no males in a population, the largest female will change sex. If smaller females were to change sex to males, the females would not breed with them--so they remain female to participate in breeding until they have grown much larger. That is why there is only one male in a given population."

Endless Ocean 2

Description

"This yellow and deep blue fish makes its home in rocks and reefs. One male will create a harem of several females in order to breed. When a male leaves a harem, the largest female will become the male. Small females cannot participate in the harem if they become males, so they continue to breed as females until they grow larger. "

Location

Endless Ocean

In Endless Ocean, bicolor angelfish can be seen under zoom-mode glows near coral-dense areas all over Manoa Lai. They seem to prefer rocky areas, like Rock Bluff.

Endless Ocean 2

These fish can be seen under zoom-mode glows in northeastern Gatama Atoll, at coordinates G-2 and G-3 (which puts them a little bit to the south of Doughnut Reef). They can also sometimes be seen at coordinates H-6, just to the south of the Private Reef Entrance.

Behavior

In Endless Ocean, these fish swim about in random patterns and are rarely seen alone; for instance, in Rock Bluff, they can often be seen in the company of a Moorish idol and a festive sea slug, with a whitespotted boxfish occasionally joining the group. In Endless Ocean 2, these fish are found alone or in pairs under zoom-mode glows, and they simply swim idly in circles.

In either game, they don't react much to being poked or petted, but they do appreciate being given food.

Notes

Real-Life Information

1/1

• Both games' descriptions report that a male bicolor angelfish will form a group of females - a harem - and that if the leading male leaves, then the biggest female will become male to take his place. This much is true, though the bicolor angelfish can also be found alone or in pairs. The trait of starting life as female and then changing to male is rather common amongst fish, including the bicolor angelfish, and is called "protogynous hermaphroditism" (pronounced pro-TAW-jeh-nuss her-MAF-ro-dye-tism).
• The family to which these angelfish belong, as mentioned in their Endless Ocean in-game description, is the family Pomacanthidae, and it encompasses all marine (ocean-dwelling) angelfish. They do indeed have the spines that the first game speaks of - these are called preopercular spines. Members of the genus that the bicolor angelfish in particular belongs to, Centropyge, are also sometimes specified as dwarf or pygmy angelfish.
  • Fish also in Pomacanthidae include the royal angelfish, the flame angelfish, the king angelfish, and the emperor angelfish.
  • The family Pomacanthidae should not be confused with the family Pomacentridae, which is home to damselfishes and anemonefishes like the sapphire devil and yellow clownfish.
  • The genus name itself, Centropyge, comes from Greek words that mean "sting" and "rear", in reference to the fact that the spines near the gills point towards the fish's tail.
• Other common names for the bicolor angelfish include oriole angelfish, two colored angelfish, blue and gold angelfish, and Pacific rock beauty angelfish.
• The bicolor angelfish is quite popular in the aquarium trade for its characteristic color combination. Aquaculturists have noted that it tends to be somewhat shy, and so needs many hiding places to feel safe; however, it has also been documented to be aggressive towards other angelfishes if the tank isn't large enough for both of them to be comfortable. Aforementioned shy behavior is also something it displays in the wild, quickly retreating into the corals it lives around if frightened.
  • Despite being collected from the wild for the aquarium trade, the bicolor angelfish is not in danger of going extinct anytime soon, according to the International Union for the Conservation of Nature. It's notoriously difficult to breed in captivity, which does put more pressure on wild populations, but not to a dangerous extent.
  • Though they are aggressive towards other angels, they are otherwise relatively peaceful.
• Bicolor angelfish like to eat algae, and will constantly be on the move to look for any rocks that have some for them to munch on. Though algae is the main part of their diet, they also like to eat small marine worms and tiny crustaceans, alongside other invertebrates. Their preference for algae helps explain their preference for a rocky habitat, because algae grows readily on rock but not so much on sand or in the open water. However, they will also take bites of the occasional coral polyp, and might nip at clams.
