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 Curious Wormfish

General information

The Curious Wormfish is a small and elongated fish that belongs to the family Gobiidae. They typically grow up to 3 inches (7.5 cm) in length and have a mottled brown or grey body with a long, slender shape. This species is found in shallow waters, such as tide pools and reef flats, and is often seen poking its head out of holes or crevices in rocks or coral.

Diet & nutrition

The Curious Wormfish is a carnivorous species that primarily feeds on small crustaceans, such as copepods and amphipods. They will also consume small fish and other invertebrates.

Determining sex

There is no reliable way to determine the sex of the Curious Wormfish by physical characteristics.

Breeding & spawning

Little is known about the breeding and spawning habits of the Curious Wormfish.

Origination

The Curious Wormfish is found in the Indo-Pacific region, including the Red Sea, east coast of Africa, and throughout the western Pacific Ocean.

Acclimation process

The Curious Wormfish should be slowly acclimated to its new environment using a drip acclimation method to avoid shock.
