Diamond Head Neon Tetra (Blue Diamond)

The Diamond Head Neon Tetra (also known as Blue Diamond Neon Tetra) is a variation of one of the aquarium hobbies most popular schooling fish, the neon tetra. The biggest difference between the two fish is that the Diamond Head does not have a blue strip down it's side. Instead, the Blue Diamond Neon Tetra has a bright blue diamond on it's forehead (between their eyes). Like most tetras, these fish prefer to be kept in schools of 5 or more in order to make them feel the most comfortable.

The Neon Tetra originally came from the streams of South America. By selective breeding, the Blue Diamond Neon Tetra was developed. To replicate their natural habitat, the use of rock work, plants, and driftwood should be included in the aquarium. We would not recommend keeping this fish with shrimp colonies due to the likeliness of the Blue Diamond Neon Tetra eating baby shrimp and potentially picking at adult shrimp.

The scientific name for the  Diamond Head Neon Tetra is Paracheirodon innesi var. "Blue Diamond"

We feed our Diamond Head Neon Tetras a mix of frozen foods including daphnia, baby brine, cyclops, and Bloodworms. We also feed a mix of Northfin flake foods, Northfin Community / Veggie pellets and live black worms.

Eye Catching

All arrived in perfect condition and are still thriving. Beautiful addition to the tank.

Very healthy, great quality fish

I ordered 11 of these beautiful diamond head neon tetras and was sent 13. They arrived quickly, and 7 days later they all have great color, they look very healthy and are eating well. I did lose one fish, which arrived in a weak state and unfortunately passed the day after arrival - it looked like swim bladder troubles. The other 12 are going strong.

Great little fish

The fish arrived healthy and did very well adjusting in my tank. Eating well and no losses so far.

A neat little upgrade from a regular Neon Tetra

Rob introduced me to the diamond head neon tetra when I was looking to build out a 20 gallon long tetra aquarium. As Im sure y'all know, the regular neon is a flashy fish but the bright diamond on this tetra's head really catches your eye! Not exactly a great defense in the wild I wouldnt think but here in my tank, a great addition. They all arrived in great health and colored up immediately.

I think I ordered a total of 72 fish. I'm not in the industry I'm just a hobbyist. Every single fish came in alive and there's at least one to two extra in the bags. The Diamond Head Tetra are spectacular!!
