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 Vagabond Butterflyfish

General information

The Vagabond Butterflyfish, also known as the Vagabond Coralfish, is a small, brightly colored marine fish found in tropical waters around the world. They can grow up to 8 inches (20 cm) in length, but are typically around 6 inches (15 cm) in aquariums. The fish is easily recognizable by its distinct coloration, which features a yellow head and black diagonal stripes on a white or silver body.

Diet & nutrition

In the wild, Vagabond Butterflyfish feed on a variety of small invertebrates, including crustaceans and coral polyps. In captivity, they should be offered a varied diet that includes frozen or live foods such as brine shrimp, mysis shrimp, and chopped seafood. They can also be fed high-quality marine flakes or pellets.

Determining sex

It is difficult to determine the sex of Vagabond Butterflyfish visually, as they do not display any external sexual dimorphism. However, in a breeding pair, the female is typically larger than the male.

Breeding & spawning

Vagabond Butterflyfish have been bred in captivity, but it is a challenging process. Breeding pairs should be introduced to a breeding tank with plenty of hiding places and a stable environment. The pair will typically spawn daily, with the male guarding the eggs until they hatch in 4-5 days. The fry can be fed on rotifers and small artemia.

Diseases

Vagabond Butterflyfish are susceptible to the same diseases as other marine fish, including ich and other parasitic infections, bacterial infections, and viral infections. Good water quality and a healthy diet can help prevent disease.

Origination

The Vagabond Butterflyfish is found in tropical waters throughout the Indo-Pacific region, including the Red Sea, East Africa, the Hawaiian Islands, and the Great Barrier Reef.

Cautions

Vagabond Butterflyfish are generally peaceful and can be kept with other non-aggressive fish. However, they may be territorial with their own species or other similar-looking butterflyfish. They are also prone to stress and should be kept in a stable and well-established aquarium.

Acclimation process

When introducing Vagabond Butterflyfish to a new aquarium, it is important to acclimate them slowly. The fish should be floated in the bag for 15-20 minutes to equalize the temperature before slowly adding small amounts of water from the aquarium to the bag over a period of 30-45 minutes. The fish should then be released into the aquarium.
