Latifasciatus Clownfish

Amphiprion latifasciatus, the Madagascar clownfish or wide-band clownfish, is a semi-aggressive, larger species of clownfish that requires a minimum 30-gallon tank for a pair.

While hardy and adaptable, their territorial nature means they are best kept as a single pair or species in most home aquariums. 

Tank Requirements & Water Parameters

Minimum Tank Size: At least 30 gallons (approx. 114 litres) for a pair. A larger tank is better, as it provides more stable water conditions and space for territorial boundaries.

Water Parameters: Stable and pristine water quality is crucial.
Temperature: 74–80°F (24–27°C).
pH: 8.0–8.4.
Salinity (Specific Gravity): 1.020–1.025.
Ammonia/Nitrite: 0 ppm.
Nitrate: < 10 ppm.

Filtration and Flow: A robust filtration system is essential. Provide moderate water flow, ensuring sheltered areas where the fish can rest. A protein skimmer can help maintain water quality.

Aquascape: Use live rock and other decorations to create hiding spots and established territories. A thin layer of crushed coral or aragonite substrate can also be used.

Anemone (Optional): In the wild, A. latifasciatus associates with the Stichodactyla mertensii anemone. However, anemones are difficult to keep and not necessary for the clownfish's survival in captivity, especially for captive-bred specimens. They will often host in large polyp corals or rockwork instead. 

Diet and Feeding

Madagascar clownfish are omnivores and should be fed a varied diet to ensure optimal health. 

Feed small amounts twice a day, offering only what they can consume within a couple of minutes.

A quality marine flake or pellet food should be a staple.

Supplement with a variety of frozen or live foods, such as mysis shrimp, enriched brine shrimp, or finely chopped seafood.

They may also graze on any algae in the tank. 

Behavior and Compatibility

Temperament: This species is semi-aggressive and highly territorial, especially the dominant female. They will defend their chosen territory (anemone, rock, etc.) and may chase other fish.

Social Structure:

They form a strict size-based dominance hierarchy. It is best to keep them as a single, mated pair. Introducing two individuals of different sizes at the same time is the best way to form a pair, as the larger one will become the female.

Tank Mates:

Choose tank mates carefully. Avoid keeping them with other clownfish species (as more aggressive types can bully smaller ones, and vice-versa) or large predatory fish like groupers or lionfish. Suitable companions include other peaceful marine fish such as some gobies, blennies, or wrasses, provided there is enough space and hiding spots.

Hardiness:

Captive-bred A. latifasciatus are generally hardy and adapt well to aquarium life, making them suitable for beginner marine aquarists who are committed to maintaining stable water conditions.
