Best for

• Planted aquariums

Behavior & Group Size

Like all Neon Tetras, this fish is a schooling species and should always be kept in groups. We recommend at least 8–12 fish for proper schooling behavior and the best visual impact.

In larger groups, their colors appear stronger and their movement becomes more natural and synchronized.

Tank Setup

Diamond Head Neon Tetras thrive in planted aquariums with moderate lighting and stable water conditions.

• Planted tank with open swimming space
• Dark substrate enhances coloration
• Moderate lighting
• Gentle to moderate flow

They look especially impressive in aquascaped tanks where lighting highlights their reflective head and body coloration.

Water Parameters

• Temperature: 22–26°C
• pH: 6.0–7.5
• Size: 3–4 cm
• Temperament: Peaceful
• Care Level: Easy

While traditionally associated with softer, acidic water, most modern Neon Tetras are well adapted to stable tap water conditions when properly acclimated.

Feeding

Diamond Head Neon Tetras are omnivores and accept a wide range of foods.

• High-quality micro pellets
• Crushed flakes
• Frozen foods such as brine shrimp or daphnia

A varied diet helps maintain their coloration and overall health.

Tank Mates

These fish are highly compatible with other peaceful species.

• Other tetras
• Rasboras
• Corydoras
• Small peaceful community fish

Avoid aggressive or much larger fish that may stress or outcompete them.

Topick Aquarium Insight

Many aquarists assume this is simply a “fancier Neon Tetra,” but the difference becomes very noticeable in a well-lit planted tank.

If you are already considering Neon Tetras, upgrading to the Diamond Head variant often gives a much more premium look with no added difficulty in care.
