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 Truncatus Anthias

General information

Truncatus Anthias are a popular and relatively hardy saltwater fish species in the aquarium trade. They are known for their bright and vibrant colors, with the males having a bright yellow tail and the females displaying more muted colors. These fish can grow up to 4 inches in length and are typically found in the Western Pacific Ocean. In aquariums, they prefer a peaceful environment with plenty of hiding places, but they are also active swimmers and require a lot of open swimming space.

Determining sex

Male Truncatus Anthias are generally larger and display more vibrant colors, with a bright yellow tail. Females are smaller and have a more subdued coloration.

Breeding & spawning

Truncatus Anthias are known to spawn in harems consisting of one male and several females. Breeding in captivity is difficult and requires specific water conditions, a balanced diet, and a peaceful environment.

Diseases

Truncatus Anthias can be susceptible to various fish diseases, including parasitic infections, bacterial infections, and fungal infections. It is important to monitor the water quality and maintain a clean environment to prevent these diseases from occurring.

Origination

Truncatus Anthias are found in the Western Pacific Ocean, specifically in the waters surrounding Japan, Taiwan, and the Philippines.

Cautions

Truncatus Anthias are generally not considered to be harmful to humans. However, they are susceptible to stress and should be handled with care during transport and acclimation to a new aquarium.

Acclimation process

When introducing Truncatus Anthias to a new aquarium, it is important to acclimate them slowly to prevent stress and shock. The drip acclimation method is recommended, which involves slowly introducing water from the aquarium into the bag containing the fish over a period of several hours.
