Green Neon Tetra – Paracheirodon simulans

The Green Neon Tetra (Paracheirodon simulans) is a tiny, peaceful nano schooling fish known for its bright green-blue shimmer, delicate size, and calm behavior. Smaller than the standard Neon Tetra, this beautiful species is a favorite for planted aquariums, nano tanks, shrimp tanks, and aquascaping setups.

Green Neon Tetras look especially stunning in planted aquariums with dark substrate, driftwood, moss, and shaded areas. Their glowing green-blue coloration adds subtle brightness and movement without overpowering a peaceful freshwater setup.

Why Choose Green Neon Tetras?

Green Neon Tetras are ideal for aquarists who want intense color in a smaller, more delicate schooling fish. Their green-blue shimmer gives them a refined look that works beautifully in natural aquascapes and planted nano aquariums.

Because they are small and peaceful, Green Neon Tetras should be kept with calm tankmates that will not outcompete or intimidate them. A group of 6–10 or more helps them feel secure and encourages natural schooling behavior.

Ideal Tank Setup

Green Neon Tetras do best in a stable, fully cycled aquarium with live plants, gentle filtration, and peaceful tankmates. Moss, floating plants, driftwood, botanicals, and darker backgrounds can help them feel secure while enhancing their coloration.

They prefer clean, stable water and are best added to established aquariums. Avoid strong current, aggressive fish, and large tankmates that may view them as food.

Compatible Tankmates

• Ember Tetras
• Other small peaceful tetras
• Small rasboras
• Phoenix Rasboras

Tankmates to Avoid

• Large predatory fish
• Aggressive cichlids
• Large angelfish that may eat small tetras

Diet & Feeding

Green Neon Tetras have tiny mouths and should be offered small, appropriately sized foods. Feed micro pellets, powdered flakes, crushed flakes, frozen baby brine shrimp, daphnia, cyclops, and other tiny foods.

A varied diet helps support strong color, healthy activity, and overall condition. Feed small portions that the group can consume quickly.
