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 False Personifer Angelfish

General information

The False Personifer Angelfish has an unusual, almost blistered appearance to its body which is generally black. The face is blue-green and the males have a speckled yellow face. A swatch of yellow covers the forehead and the caudal fin is also yellow and split with a blue-green band. This is one of the few species of angelfish where the males differ morphologically from the females. In this case, the males have a slightly longer body than females. A large tank with live rock should be provided. Not a good reef dweller, the Personifer Angelfish is prone to nip at stony and soft corals (sessile invertebrates) and clam mantles.

Diet & nutrition

This angelfish species mainly feeds on sponges, tunicates and jellyfish. In tank conditions, it may be given a varied diet consisting of frozen food such as fortified brine shrimp, mysis, and food preparations that contains sponge matter. They may also be fed with flake food containing algae such as Spirulina and Nori. It is best that the False Personifer angelfishes are introduced in a mature tank with plenty of live rock available for grazing.

Determining sex

Male and Female Chaetodontoplus meredithi are one of the few angelfish where they differ morphologically. Aside from the difference in body size, males having longer bodies than females, they also differ on the color of their faces. Males have a more blue-green face color and have speckled yellow faces, while the females have less pronounce colors on their faces.

Diseases

If not kept in tanks with optimum condition, the False Personifer agelfish are susceptible to the common saltwater diseases such as Angelfish Virus, White Spot Disease, Velvet Disease, and Head and lateral line erosion (HLLE).

Origination

Widely distributed along the Western Pacific, this angelfish species' occurrence ranges from Queensland, Australia south to New South Wales and Lord Howe Island.

Cautions

The False Personifer Species are known to nip at stony and soft corals, and clam mantles if not fed properly. They are also known to feed tubeworms. This species is not neccessarily aggresive, but it has a greater tendency towards aggresion then other species of the same genus.

Acclimation process

These angelfishes should be placed in tanks that have enough swimming space. They must intoduced in mature tanks with flimaentous algae for grazing and as hiding place.
