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 Marine Betta
General information
The Marine Betta is a popular saltwater aquarium fish that is native to the Indo-Pacific region. It has a unique, striking appearance with a black body and vivid yellow stripes. They can grow up to 8 inches in length and require a larger aquarium with plenty of hiding places to thrive. Marine Bettas are predatory fish and may eat smaller tank mates.
Diet & nutrition
In the wild, Marine Bettas feed on small fish and crustaceans. In captivity, they should be fed a varied diet consisting of frozen or live meaty foods such as brine shrimp, krill, and small pieces of fish. It is recommended to feed them small, frequent meals throughout the day.
Determining sex
It is difficult to determine the sex of Marine Bettas, as there are no external differences between males and females.
Breeding & spawning
Breeding Marine Bettas in captivity is challenging, as they require very specific water conditions and a large breeding tank. The eggs are adhesive and will stick to any surface they come into contact with.
Diseases
Marine Bettas can be susceptible to marine ich, bacterial infections, and other common saltwater fish diseases. It is important to maintain good water quality and keep stress levels low to prevent diseases.
Origination
Marine Bettas are native to the Indo-Pacific region, including the Red Sea, and can be found in coral reefs and rocky areas.
Cautions
Marine Bettas are predatory and may eat smaller tank mates. They also require a larger aquarium with plenty of hiding places to thrive, so they are not recommended for beginner hobbyists.
Acclimation process
When introducing a Marine Betta to a new aquarium, it is important to slowly acclimate them to the new water conditions over several hours to prevent shock and stress.
