Water parameters

Temp 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 Hydrogen

Measuring the acidity or alkalinity of water on a 0–14 scale, where 7 is neutral, 7 is alkaline.

NO3 1-20 ppm Nitrate

While 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 Nitrite

It is a highly toxic, intermediate compound in the nitrogen cycle produced from broken-down ammonia

PO4 0.01 - 0.1 ppm Phosphate

It is essential for plant development but must be managed, as excess levels trigger nuisance algae blooms and inhibit coral calcification.

NH3 <0.1 ppm Ammonia

It is the primary killer of aquarium fish, causing gill damage, stress, and death

Ca 380 - 450 ppm Calcium

Supporting the growth, skeletal structure, and shell formation of corals, mollusks, crustaceans, and coralline algae

KH 8 - 12 dKH Alkalinity

It acts as a shield, neutralizing acids to prevent dangerous pH "crashes" that can harm fish, corals, and plants.

Mg 1200 - 1400 ppm Magnesium

It 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 Salinity

Essential for maintaining stable, natural water parameters, proper osmoregulation, and stress-free environments for marine fish and corals

ORP 250 - 400 mV Oxidation-Reduction Potential

A higher positive mV indicates clean, oxygen-rich water with high water quality, while low readings indicate high pollution.

About Oriculate Batfish

General information

The Orbicular Batfish, also known as the Orbiculate Batfish or the Circular Batfish, is a species of saltwater fish that belongs to the Ephippidae family. It is native to the Indo-Pacific region and can be found in the waters from the eastern coast of Africa to southern Japan, down to Australia, and up to the Pacific Islands. The Orbicular Batfish is a relatively large fish that can grow up to 60 centimeters in length.

Diet & nutrition

In the wild, the Orbicular Batfish is an omnivorous fish, feeding on plankton, algae, and small fish. In captivity, it can be fed a diet of frozen or live brine shrimp, mysis shrimp, krill, and chopped seafood.

Determining sex

There are no known external differences between males and females.

Breeding & spawning

Breeding Orbicular Batfish in captivity is difficult and rare. There is no known method of breeding this species outside of the wild.

Diseases

The Orbicular Batfish is susceptible to common saltwater fish diseases such as ich, marine velvet, and bacterial infections.

Origination

The Orbicular Batfish is native to the Indo-Pacific region and can be found in the waters from the eastern coast of Africa to southern Japan, down to Australia, and up to the Pacific Islands.

Cautions

The Orbicular Batfish is generally considered a peaceful fish, but it may become territorial with age and size. It can also produce a mild toxin that can be dangerous to other fish if the Orbicular Batfish becomes stressed or injured. It is recommended to handle this fish with care and avoid housing it with small, delicate fish.

Acclimation process

The Orbicular Batfish should be acclimated slowly to the new aquarium environment over a period of a few hours to avoid shock. The water parameters of the aquarium should be checked and adjusted as necessary to match those of the fish's previous environment.
