Diamond Tetra - Moenkhausia pittieri : Complete Fish Profile & Care Guide

Table of contents


The Diamond Tetra, (Moenkhausia pittieri) is a stunning addition to any aquarium with its visually appealing colours and peaceful shoaling nature. While they can tolerate hard water, it is best to keep them in soft to medium water conditions for optimal health. Despite their excellent shoaling abilities these Tetras have a propensity to nibble on the fins of elaborate fish like Guppies, Angels and Siamese Fighters. Therefore, it is best to keep them with fish of similar size and temperament, such as Livebearers, Danios, Rasboras, and peaceful bottom dwellers like Corydoras and Plecos. They can also be great tank mates with most commonly available Gouramis and Dwarf Cichlids. The rounded shape and size of the adult Diamond Tetra also make it an ideal dither for non-aggressive Cichlids such as Geophagus and Discus. To achieve the ideal living conditions for your Diamond Tetras, they should be kept in an aquarium with dense plants, a dark substrate and dim lighting. An Amazonian biotope with driftwood branches, twisted roots and dried leaves would also provide an ideal environment for these Tetras. The Diamond Tetra 's distinguishable features include purple dorsal and anal fins, a silver body, and a noticeable red mark above the pupil of the eye, with a dark stripe running down the midline of the body. These Tetras ' namesake is attributed to their striking and iridescent scales that produce a shimmering effect along their flanks.\r\n

Natural Habitat

Diamond Tetras are found only in Lake Valencia and its surrounding waters, inhabiting the slow-moving streams abundant in vegetation and leaf litter. Sadly, industrial and agricultural pollution has caused Lake Valencia to suffer from regular algae blooms, often isolating the Diamond Tetra in shallow, vegetated parts of the lake and its tributaries. Despite the challenges they face, these stunning fish continue to thrive in their unique environment, adapting to the changing conditions and flourishing amongst the lush vegetation. Recreating the perfect environment for Diamond Tetras in your home aquarium requires a bit of effort, but the rewards are well worth it. With their striking appearance and playful personalities, Diamond Tetras are an excellent addition to any aquatic community.

2 / 2 To breed Diamond Tetras, a dedicated breeding tank with specific conditions is necessary. This should include soft water with a slightly elevated temperature and plenty of vegetation to provide shade for spawning. To produce the healthiest fry, select the strongest female and the most vibrant male and provide them with a diet rich in live food. Spawning typically occurs in the early morning, with the female laying several hundred eggs that are fertilized by the male. Once this process is complete, it 's essential to remove the parents from the tank to prevent them from consuming the eggs. Within 24 to 36 hours, the eggs will begin to hatch, and within 3 to 4 days, the fry will become free-swimming. These young fish grow at a relatively rapid pace, ensuring a beautiful addition to your aquarium in no time.

Diet & feeding

In a captive setting, it is observed that Diamond Tetras exhibit a hearty appetite and will readily consume various types of fish food, including flakes, granules and small pellets. They also derive nutritional benefits from a varied diet of live and frozen foods such as Bloodworm and Daphnia. Incorporating such nutritious offerings will not only contribute to their overall well-being but also enhance their natural colors and condition.
