There are a few species of fish that exhibit yellow and pink striping patterns. The most well-known is likely the yellowtail clownfish, which is popular in home aquariums. Other fish with similar coloration include certain damselfish, wrasse, and angelfish species.
Yellowtail Clownfish
The yellowtail clownfish (Amphiprion clarkii) is one of the most recognizable fish species due to its bright color pattern. As their name suggests, these fish have a yellow stripe running horizontally across the rear half of their bodies. They also have thin pink stripes just above the yellow band. The rest of the body is orange with three thick white bands – one at the head, midsection, and tail.
Yellowtail clownfish are native to the coral reefs of Southeast Asia and Australia. They live symbiotically with sea anemones, having a layer of protective mucus that allows them to move freely among the anemone’s stinging tentacles. In the wild, yellowtail clownfish have an intricate social hierarchy where one dominant breeding pair resides in each anemone. The other fish in the group are non-breeding males that act as helpers.
In the aquarium trade, yellowtail clownfish are bred commercially rather than taken from reefs. They are quite hardy, adapting well to captivity. A 30-40 gallon tank with plenty of live rock and hiding spots is suitable for a pair. They should be fed a varied diet of meaty foods like mysis shrimp, vitamin-enriched brine shrimp, and quality flake/pellet foods. With good care, yellowtail clownfish can live 5-10 years in an aquarium.
Other Fish With Similar Markings
While the yellowtail clownfish is the most famous, several other marine fish share the characteristic yellow and pink horizontal striped pattern. These include:
- Pink skunk clownfish (Amphiprion perideraion) – Orange body with one thick pink stripe and a thin yellow stripe below it
- Sebae clownfish (Amphiprion sebae) – Orange with yellow midsection band bordered by pink strips above and below
- Spinecheek anemonefish (Premnas biaculeatus) – Has broader pink and yellow stripes compared to clownfish
- Redfin butterflyfish (Chaetodon lunulatus) – Silvery-gray body with yellow rear stripe and reddish-pink stripe above it
- Sunset wrasse (Thalassoma lutescens) – Iridescent green body with bright yellow stripe at the caudal peduncle (base of the tail)
- Yellowhead jawfish (Opistognathus aurifrons) – Pinkish body with lemon yellow head and dorsal fin
- Ornate angelfish (Genicanthus bellus) – Black body with curved pink and yellow horizontal stripes
There are also freshwater fish with similar markings, such as:
- Black ruby barb (Puntius nigrofasciatus) – Silvery fish with a black stripe bordered by a pink stripe above and thick yellow stripe below
- Panda garra (Garra flavatra) – Black with a yellow midsection stripe and pink markings on its fins
The Yellowtail Clownfish in Detail
Now that we’ve covered some of the other fish with yellow and pink stripes, let’s take a more in-depth look at the yellowtail clownfish specifically:
Scientific Name and Classification
The yellowtail clownfish has the scientific name Amphiprion clarkii. Its genus, Amphiprion, includes around 30 valid species commonly known as anemonefishes or clownfish. A. clarkii belongs to the family Pomacentridae, which contains around 320 species of damselfish and clownfish.
Physical Description
As described earlier, yellowtail clownfish have vivid orange bodies with white bands at the head, midsection, and tail. They get their name from the broad, lemon yellow stripe that runs horizontally across the rear half of the body. Right above the yellow band are two thin pink stripes. The tail fin is also yellow with pink tips.
Yellowtails are medium-sized clownfish, growing to around 4 inches in length. Males are slightly larger than females on average. They have an oval-shaped, compressed body well-suited for squeezing into coral crevices. Their fins are rounded. Yellowtail clownfish can live for 5-10 years with proper care.
Habitat and Ecology
In the wild, yellowtail clownfish inhabit coral reefs in the tropical and sub-tropical waters of Southeast Asia. Their range extends from the eastern Indian Ocean to the western Pacific. Specifically, they are found from Indonesia to the Philippines, New Guinea, and northern Australia.
Yellowtails live in a mutualistic symbiosis with certain sea anemone species. By swimming among the anemone’s stinging tentacles, they gain protection from predators. A mucus coating on their skin prevents them from being stung. In return, the clownfish chase away butterflyfish and other anemone predators. Their bright coloring also lures prey toward the anemone.
Clownfish form social groups centered around a single anemone, with a size-based hierarchy. The largest breeding female is the dominant individual, and the breeding male is second in the hierarchy. The other fish in the group are non-breeding males that help maintain the territory. If the female dies, the breeding male will change sex and become the new dominant female.
Omnivorous in nature, the yellowtail clownfish feeds on small zooplankton, algae, larvae, and the tentacles of their host anemones. Anemones help remove parasites from the clownfish as well.
Behavior
Yellowtail clownfish are highly territorial around their host anemone. They will vigorously chase away other fish that encroach on their area, even those much larger in size. Within the group, they express dominance through behaviors like chasing, fin displays, and jostling for position in the anemone.
If their anemone is disturbed or destroyed, yellowtail clownfish will seek out a new host. They can swim relatively fast over short distances. Generally peaceful when kept with appropriate tank mates, yellowtails may become aggressive if kept in too small of an aquarium.
Breeding and Life Cycle
In preparation for spawning, the male yellowtail clownfish prepares a nest site near the anemone by carefully cleaning a bare rock surface. After a courtship dance, the female lays between 100-1,000 eggs that adhere to the nest site. The male fertilizes the eggs and provides parental care by aerating them and removing debris.
The eggs hatch after 6-8 days, becoming tiny larvae that drift out with ocean currents. This planktonic stage lasts around two weeks. The larvae then metamorphose into the juvenile form and return to a suitable anemone. They reach maturity after around one year.
Importance to Humans
Due to their beauty and close relationship with anemones, yellowtail clownfish have long been prized by aquarists. They were among the first marine fish species bred in captivity on a commercial scale. Most yellowtails in the aquarium trade are tank-raised.
In the wild, yellowtail clownfish play an important role in reef ecology through their symbiosis with anemones. As planet’s coral reefs face threats like pollution, overfishing, and climate change, the plight of anemonefish highlights the urgent need for marine conservation.
Keeping Yellowtail Clownfish in Aquariums
Here are some key tips for successfully keeping yellowtail clownfish in a home saltwater aquarium:
- Get a bonded pair – they are less aggressive and easier to care for than groups
- Minimum 30 gallon tank, give them plenty of swimming space
- Include lots of rocky hiding places and overhangs
- Use a quality protein skimmer, filtration system and perform water changes
- Maintain good water quality – SG 1.023-1.025, pH 8.1-8.4, temp 74-80F
- Feed a varied carnivorous diet – mysis shrimp, brine shrimp, pellets, greens
- Include host anemones like bubble tip or carpet anemone
- Avoid housing with semi-aggressive fish like triggers and large angels
- Quarantine new fish and observe for signs of disease
- Provide dim lighting that mimics their natural reef environment
With the proper setup and care, yellowtail clownfish are hardy, long-lived, and interactive aquarium residents. Their bright colors and animated movements delight aquarists of all levels. Be sure to closely research their needs before bringing some home!
