Black Skirt Tetra Fish

The Black Skirt Tetra—often called the Black Tetra—is a peaceful, schooling fish known for its striking black “skirt” along the bottom fin. These active swimmers love to feast on live daphnia, which helps keep them healthy and active. Their silver bodies and black bottom fins bring lively motion to a community aquarium.

About Black Tetras

• Keep them in groups of 6 or more for a vibrant and active atmosphere.
• Black Tetras grow to a maximum size of 3 inches, making them perfect for smaller aquariums.
• Black Skirt Tetra live between 3 to 5 years, but we usually sell them at around 1 year old so they can adjust easier to their new home.
• Best suited for planted aquariums due to their timid personality.
