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 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 Molly Miller Blenny
General information
The Molly Miller Blenny, also known as the Combtooth Blenny, is a small, colorful species that can grow up to 3 inches (8 cm) in length. This species is found in the western Atlantic Ocean, from the Bahamas to the Gulf of Mexico. They are a hardy species and can adapt well to life in captivity.
Diet & nutrition
The Molly Miller Blenny is an omnivorous species that feeds on a varied diet of both meaty and plant-based foods. In the wild, their diet consists of small crustaceans, plankton, and algae. In captivity, they can be fed a diet of frozen or live brine shrimp, mysis shrimp, and spirulina-based flake foods.
Diseases
Molly Miller Blennies are generally hardy and not prone to any specific diseases. However, they can be susceptible to common aquarium diseases like ich and fin rot, especially if water quality is not properly maintained.
Origination
The Molly Miller Blenny is found in the western Atlantic Ocean, from the Bahamas to the Gulf of Mexico.
Cautions
Molly Miller Blennies are not known to be harmful to humans or other fish species.
Acclimation process
When introducing a Molly Miller Blenny to a new aquarium, it is important to acclimate them slowly to their new environment. The drip acclimation method is recommended to prevent stress and shock.
