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 Radiata Lionfish
General information
Has red, white, and black vertical stripes along the body; large, fan-like pectoral fins; and tall, quill-like dorsal fins. A medium or larger aquarium with numerous caves or overhangs hiding places is suitable. Should not be kept with overly aggressive tank makes that may interfere with its feeding.
The Pterois radiata lionfish can grow to 9.4 in. (24 cm).
They can be kept in pairs or in small groups in a large aquarium.
Diet & nutrition
Carnivor - In the wild, the Pterois radiata lionfish feeds entirely on crustaceans. When first introduced into the aquarium, live saltwater feeder shrimp should be used to entice this fish to eat. The Radiata Lionfish diet consists of meaty foods. Wild caught lionfish can be difficult to feed initially try feeding different live food such as:
- Grass shrimp
- Freshwater crayfish
- Fiddler crabs
- Small fish
Feed 3-4 times a week.
Determining sex
It's very difficult to sex Lionfish there does not seem to be a way to determine sex by their appearance.
Breeding & spawning
Breeding in captivity has so far been unsuccessful.
Diseases
Lionfish are hardy fish, if provided with good water conditions and feed well, almost never contract diseases or parasites. The most common disease problems seen in Lionfish are fin rot, cloudy eyes, and dinoflagellates. Lionfish do get ich, and this condition can be treated with hyposalinity or copper based medications.
Origination
Indo-Pacific - commonly found in South Africa and the Red Sea to Indonesia.
Cautions
Will eat ornamental shrimp and smaller fish.
Has venomous spines.
Acclimation process
It will hide while acclimating to its new environment.
