Green Neon Tetra – Paracheirodon simulans

Small, peaceful, and brilliantly iridescent, the Green Neon Tetra (Paracheirodon simulans) is a stunning freshwater schooling fish admired for its vivid blue-green stripe and subtle red undertones. Closely related to the classic Neon Tetra, this species is slightly smaller and glows with an emerald sheen that truly pops in planted aquariums.

Green Neon Tetras are calm, easy to care for, and thrive in soft, acidic water with dim lighting — making them ideal for blackwater or natural aquascape setups. Their elegant schooling behavior and color intensity make them a favorite among nano tank and planted tank enthusiasts.
