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 Green Canary Blenny
General information
The Green Canary Blenny is a small, peaceful saltwater fish that can grow up to 3 inches in length. It has a vibrant green coloration with a yellow underside, and a unique elongated body shape. These blennies are commonly found in coral reefs and rocky areas throughout the Indo-Pacific region.
Diet & nutrition
The Green Canary Blenny is an omnivore that feeds on a variety of small crustaceans, algae, and plankton. In captivity, they can be fed a diet of frozen or live brine shrimp, mysis shrimp, and other meaty foods.
Determining sex
There is no visible difference between male and female Green Canary Blennies.
Breeding & spawning
Breeding Green Canary Blennies in captivity is challenging and requires specialized breeding techniques.
Diseases
Green Canary Blennies are generally hardy fish and are not prone to any specific diseases. However, as with all aquarium fish, they are susceptible to common diseases such as ich and velvet.
Origination
The Green Canary Blenny is native to the Indo-Pacific region, including Tonga, Fiji, Samoa, and the Great Barrier Reef.
Cautions
The Green Canary Blenny has venomous fangs that it uses for self-defense. While not lethal to humans, their bite can be painful and can cause swelling and numbness.
Acclimation process
Proper acclimation is crucial when introducing a new Green Canary Blenny into an aquarium. Slowly drip acclimate the fish over a period of 1-2 hours to allow it to adjust to the water parameters.
