Temperature
Maintaining a stable and appropriate temperature is critical for the survival of aquatic life.
pH 7.8 - 8.4 potential of HydrogenMeasuring the acidity or alkalinity of water on a 0–14 scale, where 7 is neutral, 7 is alkaline.
NO3 1-20 ppm NitrateWhile 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 NitriteIt is a highly toxic, intermediate compound in the nitrogen cycle produced from broken-down ammonia
PO4 0.01 - 0.1 ppm PhosphateIt is essential for plant development but must be managed, as excess levels trigger nuisance algae blooms and inhibit coral calcification.
NH3 <0.1 ppm AmmoniaIt is the primary killer of aquarium fish, causing gill damage, stress, and death
Ca 380 - 450 ppm CalciumSupporting the growth, skeletal structure, and shell formation of corals, mollusks, crustaceans, and coralline algae
KH 8 - 12 dKH AlkalinityIt acts as a shield, neutralizing acids to prevent dangerous pH "crashes" that can harm fish, corals, and plants.
Mg 1200 - 1400 ppm MagnesiumIt 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 SalinityEssential for maintaining stable, natural water parameters, proper osmoregulation, and stress-free environments for marine fish and corals
ORP 250 - 400 mV Oxidation-Reduction PotentialA higher positive mV indicates clean, oxygen-rich water with high water quality, while low readings indicate high pollution.
About Eastern Hulafish
General information
The Eastern Hulafish is a small saltwater fish that grows up to 10 cm in length. It has a slender, elongated body with a pointed snout, and its coloration is predominantly white with narrow, vertical stripes in shades of blue, black, and yellow. This species is generally peaceful and can be kept in a community aquarium with other peaceful fish. It is recommended to keep them in a tank with a sandy substrate and plenty of hiding places.
Diet & nutrition
The Eastern Hulafish is carnivorous and should be fed a diet of meaty foods such as small crustaceans, brine shrimp, and other small marine invertebrates.
Determining sex
There are no known external differences between male and female Eastern Hulafish.
Breeding & spawning
There is limited information on breeding and spawning in captivity for the Eastern Hulafish.
Diseases
The Eastern Hulafish is generally hardy and disease-resistant. However, like all fish, it is susceptible to common aquarium diseases such as Ich and Velvet.
Origination
The Eastern Hulafish is found in the Western Pacific Ocean, specifically in the waters around Australia and New Zealand.
Acclimation process
When acclimating the Eastern Hulafish to a new aquarium, it is important to slowly acclimate it to the new water conditions by floating the bag in the aquarium for 20-30 minutes to equalize the temperature, and then slowly adding small amounts of aquarium water to the bag over a period of time.
