Green Neon Tetra – Paracheirodon simulans The Green Neon Tetra is a small, peaceful fish that loves being in groups. It’s a close cousin to the Neon Tetra but slimmer, and that green-blue line across its body really shines in planted aquariums. They’re hardy, easy to care for, and great for community setups. product Description These little guys come out of the blackwater streams of the Amazon, places with soft, slightly acidic water and heaps of plants and roots. They’re tiny — barely hit 2.5 cm (about an inch), so they stay smaller than your regular Neon Tetras. But don’t let the size fool you, when the tank lights catch that green-blue stripe, it looks unreal, almost like they’re glowing. In a planted tank they really stand out, even though they’re small. Best way to keep them is in a proper school — six or more at least. They don’t do well solo, they’re wired to swim in groups and that’s when you see them looking natural and relaxed. When they move together, it’s like a little shimmer show across the tank. Feeding’s simple too — flakes, micro pellets, or frozen bits like brine shrimp and daphnia. They’re not picky eaters. Basically, if you’re after a splash of color that doesn’t take up space and doesn’t make your life difficult, these little guys tick all the boxes.
