Water parameters
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 Blue Gudgeon Dartfish
General information
The Blue Gudgeon Dartfish (Ptereleotris heteroptera) is a small, peaceful fish that can grow up to 3 inches in length. They are commonly found in the Western Pacific Ocean, specifically around Indonesia and the Philippines. They are known for their bright blue coloration and elongated body, which allows them to dart in and out of small crevices and rock formations.
Diet & nutrition
The Blue Gudgeon Dartfish is a carnivorous species and should be fed a varied diet that includes both live and frozen foods. They will readily consume small meaty foods such as brine shrimp, mysis shrimp, and other small crustaceans.
Determining sex
There is no visible difference in appearance between male and female Blue Gudgeon Dartfish.
Breeding & spawning
Breeding the Blue Gudgeon Dartfish in an aquarium setting is challenging and has not been documented extensively. They are known to be mouthbrooders, with the male carrying the eggs in his mouth until they hatch.
Diseases
The Blue Gudgeon Dartfish is generally a hardy species and is not susceptible to any specific diseases. However, as with all fish, they can be affected by common diseases such as ich or velvet if proper water conditions and care are not maintained.
Origination
The Blue Gudgeon Dartfish is native to the Western Pacific Ocean, specifically around Indonesia and the Philippines.
Cautions
The Blue Gudgeon Dartfish is generally a peaceful species and is compatible with most other reef-safe fish species. However, they may become aggressive towards their own kind or other similar-looking species.
Acclimation process
Proper acclimation is important for all fish species, including the Blue Gudgeon Dartfish. It is recommended to slowly drip acclimate them over a period of 1-2 hours to help them adjust to the new water conditions.
