NO3 1-20 ppm NitrateWhile 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 NitriteIt is a highly toxic, intermediate compound in the nitrogen cycle produced from broken-down ammonia
PO4 0.01 - 0.1 ppm PhosphateIt is essential for plant development but must be managed, as excess levels trigger nuisance algae blooms and inhibit coral calcification.

About Geometric Pygmy Perchlet
General information
The Geometric Pygmy Perchlet is a small saltwater fish that usually grows up to 3 inches in length. It is suitable for keeping in small to medium-sized aquariums, as it prefers a water temperature range of 72-78°F and a pH range of 8.1-8.4. This species is known for its beautiful geometric patterns, which can vary depending on its gender and location of origin.
Diet & nutrition
The Geometric Pygmy Perchlet is carnivorous and mainly feeds on small crustaceans and other invertebrates. In captivity, they can be fed a diet consisting of frozen or live brine shrimp, mysis shrimp, and other small meaty foods. It's important to provide a varied diet to ensure that they receive all the necessary nutrients.
Determining sex
It can be difficult to determine the sex of Geometric Pygmy Perchlets visually. However, males may have more vivid colors and larger dorsal fins than females.
Breeding & spawning
There is limited information available on the breeding and spawning of Geometric Pygmy Perchlets in captivity.
Diseases
Geometric Pygmy Perchlets are generally hardy and not prone to specific diseases. However, they can be susceptible to common aquarium diseases such as ich or fin rot. It's important to maintain good water quality and provide a balanced diet to prevent diseases.
Origination
The Geometric Pygmy Perchlet is native to the western Pacific Ocean, specifically in areas such as Japan, Indonesia, and the Philippines.
Cautions
The Geometric Pygmy Perchlet is generally considered safe for aquariums. However, they are known to be aggressive towards other similar-looking species, so it's important to keep them with peaceful tank mates.
Acclimation process
When introducing Geometric Pygmy Perchlets to a new aquarium, it's important to acclimate them slowly to prevent shock. This can be done by floating the bag containing the fish in the aquarium for about 15-20 minutes, gradually adding small amounts of aquarium water to the bag. This process allows the fish to adjust to the new water parameters.
