Head & Tail Light Tetra (Hemigrammus ocellifer)
The Head & Tail Light Tetra (Hemigrammus ocellifer) is a peaceful, attractive freshwater schooling fish named for the two distinctive reflective “light” spots located near the eye and at the base of the tail. These markings shimmer under aquarium lighting, making the species especially appealing in planted community aquariums.
Calm and social by nature, Head & Tail Light Tetras thrive when kept in groups and show their best colour and confidence in stable, well-maintained aquariums. Their gentle temperament makes them an excellent choice for peaceful community setups.

I added a group of five Head & Tail Light Tetras to my 50-liter planted tank. They’ve been active and colorful since day one. The reflective spots shine beautifully under LED lighting, and they swim together in a calm, coordinated way. Great for a peaceful community setup.

The fish arrived healthy and seem to adjust well to my tank conditions. I noticed their spots glow more in the morning light. They don’t chase other fish and stay near the middle of the tank, which is ideal for a balanced community.

I’ve kept these tetras for three months now. They’re very active during the day and form a tight school. The silver body and glowing spots make the tank look more dynamic. Easy to care for and very peaceful.
