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 Burgess Butterflyfish

General information

The Burgess Butterflyfish, also known as the Blue Mask Butterflyfish, is a popular saltwater aquarium fish that is native to the western Pacific Ocean. It has a bright yellow body with a blue face mask and a black diagonal stripe on the lower half of its body. It can grow up to 8 inches (20 cm) in length and is a hardy species that can adapt to a range of water conditions.

Diet & nutrition

The Burgess Butterflyfish is an omnivore and feeds on a variety of foods including algae, small crustaceans, and invertebrates. In captivity, it can be fed a diet of frozen or fresh meaty foods such as brine shrimp, mysis shrimp, and chopped seafood, as well as algae-based foods.

Determining sex

There are no visible differences between males and females of the Burgess Butterflyfish species.

Breeding & spawning

Breeding and spawning of Burgess Butterflyfish in captivity is rare. In the wild, they spawn in pairs and lay their eggs on hard surfaces such as rocks or coral.

Diseases

The Burgess Butterflyfish is susceptible to common saltwater fish diseases such as ich, marine velvet, and bacterial infections. It is important to maintain good water quality and provide a healthy diet to help prevent these diseases.

Origination

The Burgess Butterflyfish is native to the western Pacific Ocean, including Japan, Micronesia, and the Great Barrier Reef.

Cautions

The Burgess Butterflyfish can be aggressive towards other butterflyfish and may require a larger aquarium with plenty of hiding places to help reduce aggression. It may also nip at corals and other invertebrates in the aquarium.

Acclimation process

It is important to acclimate the Burgess Butterflyfish slowly to its new aquarium environment to reduce stress and improve its chances of survival. The drip acclimation method is recommended, which involves slowly introducing aquarium water to the fish over a period of time.
