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 Kamohara Blenny

General information

The Kamohara Blenny is a small and colorful species of blenny that is native to the western Pacific Ocean, specifically in Japan and the Ryukyu Islands. It has a slender body with bright yellow and black stripes running along its sides, and is known for its unique fang-like teeth that it uses for self-defense. In the wild, it can reach up to 3.5 cm in length and is a popular addition to reef aquariums due to its vibrant colors and active behavior.

Diet & nutrition

The Kamohara Blenny is a carnivorous species that feeds primarily on small crustaceans such as copepods and amphipods. In captivity, they can be fed a varied diet that includes frozen and live foods such as brine shrimp, mysis shrimp, and chopped seafood. It is important to ensure that the diet is nutritionally balanced to maintain the health and longevity of the fish.

Determining sex

There are no significant visual differences between males and females of the Kamohara Blenny species.

Breeding & spawning

Kamohara Blennies are egg layers, and spawning is known to occur in the wild. However, breeding in captivity is rare, and there are no known techniques for inducing spawning.

Diseases

Kamohara Blennies are generally hardy and resistant to most common diseases. However, like all saltwater fish, they are susceptible to marine ich and other parasitic infections if proper water quality and husbandry are not maintained.

Origination

The Kamohara Blenny is native to the western Pacific Ocean, specifically in Japan and the Ryukyu Islands.

Cautions

The Kamohara Blenny has venomous fangs that it uses for self-defense. While they are not aggressive towards humans, care should be taken when handling the fish or when working in the aquarium to avoid accidental bites.

Acclimation process

Like all saltwater fish, the Kamohara Blenny should be acclimated slowly to its new environment to minimize stress and the risk of disease. This can be achieved by slowly adding water from the aquarium to the bag or container holding the fish over a period of several hours before introducing it into the main tank.
