Black Neon Tetra Diamon Head

Black Neon Tetra – Hyphessobrycon herbertaxelrodi

The Black Neon Tetra, sometimes called “Diamond Head,” is a sleek little fish with bold black and silver stripes and a shimmer on its forehead that really stands out under aquarium lights. They’re calm, active schooling fish and fit right into planted community tanks.

Product ,Description

These guys come from the Paraguay basin down in South America, usually hanging around shaded streams with plants and roots all over. In tanks they don’t get big, maybe 4 cm (about an inch and a half), but that sharp black and silver stripe with the little glow on the head makes them pop out straight away. Even in a busy tank they’re easy to spot.

Best way to keep them is in a school of six or more. When they all move together, the tank feels alive, like the whole thing’s got motion going on. With decent water and a bit of care they’ll usually go on for around 5 years, sometimes even longer if things are kept steady.

They’re pretty chill fish, not the type to go after others, and they’re not picky at all with food. Flakes, small pellets, frozen stuff like brine shrimp — they’ll eat most things. Because they handle different setups well and don’t give you too much hassle, they’re good for beginners but also solid for anyone who just wants a peaceful, easy-going fish in their community tank.
