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 Blue Flasher Wrasse
General information
The Blue Flasher Wrasse has some amazing color, spectacular finnage and dynamic activity. In fact, the boisterous activity of the Blue Flasher Wrasse can embolden shy fishes to spend more time in the open.

Similar to other Flasher Wrasse, the social and gregarious Blue Flasher Wrasse prefers to occupy the open water column. However, the Blue Flasher Wrasse will benefit from rockwork aquascaped with plenty of caves and crevices where a quick retreat is possible if threatened.

Cautions
Wrasse are considered jumpers make sure your aquarium has a tight-fitting canopy or screen cover to prevent the Wrasse from jumping out of your aquarium. Wrasse have been known to jump through the smallest of holes in a canopy.
Wrasses prefer to have a 2″ (5cm) sandbed to allow them to burrow into the sand to sleep or when they feel like they are in danger. Some people with bare bottom tanks have also added a Tupperware with a 2″ deep sand bed to accommodate the wrasse’s needs.
They are generally peaceful but may display aggression towards members of the same species.
