Water parameters

Temp 76-80 F Temperature

Maintaining a stable and appropriate temperature is critical for the survival of aquatic life.

pH 7.8 - 8.4 potential of Hydrogen

Measuring the acidity or alkalinity of water on a 0–14 scale, where 7 is neutral, 7 is alkaline.

NO3 1-20 ppm Nitrate

While less toxic than ammonia, high nitrate levels (above 40–80 ppm) are important to monitor because they can cause fish stress, stunted growth, and harmful algae blooms.

NO2 <0.0001 ppm Nitrite

It is a highly toxic, intermediate compound in the nitrogen cycle produced from broken-down ammonia

PO4 0.01 - 0.1 ppm Phosphate

It is essential for plant development but must be managed, as excess levels trigger nuisance algae blooms and inhibit coral calcification.

NH3 <0.1 ppm Ammonia

It is the primary killer of aquarium fish, causing gill damage, stress, and death

Ca 380 - 450 ppm Calcium

Supporting the growth, skeletal structure, and shell formation of corals, mollusks, crustaceans, and coralline algae

KH 8 - 12 dKH Alkalinity

It acts as a shield, neutralizing acids to prevent dangerous pH "crashes" that can harm fish, corals, and plants.

Mg 1200 - 1400 ppm Magnesium

It enables coral growth by supporting skeletal formation, assists in metabolic processes, and ensures that calcium is available for corals, clams, and coralline algae.

SG 1.023 - 1.026 SG Salinity

Essential for maintaining stable, natural water parameters, proper osmoregulation, and stress-free environments for marine fish and corals

ORP 250 - 400 mV Oxidation-Reduction Potential

A higher positive mV indicates clean, oxygen-rich water with high water quality, while low readings indicate high pollution.

About Bali Lunate Anthias

General information

Commonly known as Bali Lunate Anthias, Pseudanthias cf lunulatus is a beautiful and peaceful reef fish that belongs to the family Serranidae. 
Bali Lunate Anthias is a small-sized fish that can grow up to 3 inches (7.5 cm) in length. It has a bright orange-pink colored body with a crescent-shaped tail, which gives it its common name. It is a popular species for aquarium enthusiasts due to its beautiful coloration and peaceful nature.

Diet & nutrition

In the wild, Bali Lunate Anthias feeds on planktonic crustaceans and other small marine invertebrates. In captivity, it can be fed a varied diet of frozen and live foods such as brine shrimp, mysis shrimp, and copepods.

Determining sex

The males of this species are usually more colorful than the females. The males have a brighter orange coloration and a more pronounced crescent-shaped tail.

Breeding & spawning

Bali Lunate Anthias is a hermaphroditic species, which means that they can change their sex from female to male. They are known to form harems with one dominant male and several females. Breeding this species in captivity is challenging and requires specific conditions.

Diseases

Bali Lunate Anthias can be prone to marine ich and other common saltwater fish diseases. It is important to maintain high water quality and a stress-free environment to prevent diseases.

Origination

Bali Lunate Anthias is found in the Western Pacific Ocean, particularly in Indonesia and the Philippines.

Cautions

Bali Lunate Anthias is a peaceful species and can be kept with other non-aggressive fish. However, it is important to note that it can be intimidated by larger or more aggressive fish, which can lead to stress and disease.

Acclimation process

When introducing Bali Lunate Anthias to a new aquarium, it is important to acclimate them slowly to prevent stress and disease. This can be done by slowly adding small amounts of water from the aquarium to their shipping bag over a period of several hours.
