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 Lemon Chromis
General information
The Lemon Chromis, also known as the Ternate Damsel, is a popular species in the aquarium trade due to its bright yellow coloration. It has a slender body and can grow up to 3 inches (7.5 cm) in length. In the wild, these fish can be found in coral reefs in the Indo-Pacific region.
Diet & nutrition
In the aquarium, Lemon Chromis should be fed a varied diet of high-quality flake food, frozen or live brine shrimp, and mysis shrimp. They may also eat small amounts of algae and copepods.
Determining sex
It is difficult to determine the sex of Lemon Chromis visually as males and females look similar.
Breeding & spawning
Lemon Chromis are known to be prolific spawners and will spawn in the aquarium under the right conditions. However, raising the fry can be challenging.
Diseases
Lemon Chromis can be susceptible to various aquarium diseases, including ich and marine velvet. It is important to maintain good water quality and avoid overcrowding to prevent diseases.
Origination
Lemon Chromis are native to the Indo-Pacific region, specifically the waters around Indonesia and the Philippines.
Cautions
Lemon Chromis are generally peaceful and can be kept with other non-aggressive fish. However, they may become territorial and aggressive towards other fish of the same species or similar appearance.
Acclimation process
When introducing Lemon Chromis to a new aquarium, it is important to acclimate them slowly to the new water parameters. This can be done by slowly adding small amounts of aquarium water to their transport bag over the course of 1-2 hours.
