Blackfin Coralfish
(Chelmon muelleri)

Descrição

The user wants a product description for *Chelmon muelleri*. I have gathered the following information:

* **Scientific Name:** *Chelmon muelleri*
* **Common Name:** Blackfin Coralfish, Muller’s Coralfish, Müller’s Coralfish, Beaked Coralfish, Highfin Coralfish, Australian Longnose Butterflyfish. “Blackfin Coralfish” and “Muller’s Coralfish” seem most prevalent.
* **Maximum Size:** 20.5 cm (8.1 inches), 20 cm (7.9″), 7 inches (18 cm), 15.2-17.8 cm (6-7″), 18 cm, 7″. I’ll go with 18-20 cm.
* **Origin:** Endemic to Australia, specifically coastal reefs and estuaries of Queensland and northwestern Australia (Kimberley Island groups). Also referred to as Coral Sea.
* **pH Range:** 8.0-8.5, 8.1-8.4, 8.3. I’ll use 8.1-8.4.
* **Temperature:** 21-27°C (70-82°F), 20-25°C (68-77°F), 25-28.8°C (mean 27.4°C), 68-77°F. I’ll use 21-27°C.
* **Lifespan:** 9-10 years.
* **Swimming Zone:** Often found exploring crevices in rockwork. Implies mid-to-bottom but also open swimming space needed. Butterflyfish generally are mid-level swimmers but forage everywhere. I’ll stick to mid.
* **Care Level:** Hardy, Suitable with care, Moderate Difficult, Moderate, Intermediate, Difficult, Experts only! Very hard to keep. There is a wide range of care levels, leaning towards moderate to difficult. It’s often difficult to get them feeding initially. I will lean towards ‘Difficult’ to promote responsible buying.
* **Temperament:** Shy and docile, Peaceful, Semi-aggressive (can nip timid fish, battle same genus). Generally peaceful, but territorial with conspecifics and similar genera. I’ll describe it as peaceful but cautious with conspecifics.
* **Compatibility:** Can coexist as a pair if introduced simultaneously. Ignores most other fish, generally peaceful, but cautious with similar species. Best kept singly or as a male/female pair. Not with other Butterflyfish or stress-inducing fish. May pick at soft corals, tube worms, crustaceans, clam mantles if not well fed. May nip at feather dusters and anemones. Known to eat Aiptasia anemones, but not always. Not recommended for reef aquariums as they likely consume coral polyps. Reef safe with caution. Not reef safe. I will state reef safe with caution due to potential nipping at invertebrates and some corals.
* **Tank Size:** 700 L (185 gal), 75 gallons (284 L) or larger, 100 gallons (378 L), 473 Litres (125 US G), 125 gallons (473 L), 501 to 1000 Litres, 300 L, at least 1000 Liter. There is a significant range. The consensus for a single fish seems to be around 300-500L, with larger for pairs or long-term health. I will use 450L (around 120 gallons) as a good minimum, acknowledging larger is better.
* **Diet:** Carnivorous. Eats tubeworms. Must be fed varied diet. Thrives with micro life (copepods, amphipods). Requires frequent feeding. Eats slowly, selective feeder. Can be difficult to get eating. Live zooplankton or live mussels/crushed shells initially. Meaty foods: live fortified brine, mysis shrimp, black/red worms. Stuff food into crevices to mimic natural feeding. Will also eat worms, clams, tunicates, crustaceans. May accept flake food. Frozen foods over time. Varied diet of frozen meaty foods, adding algae. Carnivore, flourishing on diverse diet (Gamma Foods recommended).
* **Appearance:** Silvery white background with four wide brown/russet vertical bars and a large black ocellus (false eyespot) at the base of the posterior dorsal fin. Distinctive elongated snout. Black fins. Dusky dark color highlighted with orange vertical stripes.
