Diamond Tetra ML – Moenkhausia pittieri

Diamond Tetra ML, scientifically known as Moenkhausia pittieri, is a stunning freshwater fish prized for its sparkling, iridescent scales that resemble tiny diamonds under light. Native to Venezuelan freshwater systems, this species is highly valued for its elegant appearance and graceful swimming behavior.

The “ML” size refers to medium-large specimens, typically well-grown individuals that display enhanced coloration and more developed finnage. Mature males are especially impressive, showing extended dorsal and anal fins along with stronger shimmering effects, while females are slightly rounder with a subtler shine.

When kept in groups, Diamond Tetras create a glittering display as they swim together, reflecting light from different angles. This makes them a perfect choice for planted aquariums and aquascapes, where lighting can highlight their dazzling scales.
